0000436715 00000 n Boost, nitrous, and race fuel throw all kinds of variables into the overall combustion equation. Tired of smelling like gas instead of nice fresh cut grass when you come in from working on the lawn? MSD Cross Reference with DENSO Stock Number to Plug Type. Eventually, it's cooled by the radiator. It fits domestic applications in the 80s to early 90s, and is widely stocked in automotive retail stores. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. After a change is made, a new set of plugs are installed (you cannot re-read used plugs accurately), and you repeat your test run. Spark plugs act as a heat exchanger, pulling thermal energy away from the combustion chamber and transferring it to the engines cooling system. Image Part No. 2? Your browser either does not have JavaScript enabled or does not appear to support enough features of JavaScript to be used well on this site. Consult your owners manual for the right spark plug for your car. 0000434006 00000 n Our spark plugs have been improving engine performance since 1907. If there's any more fuel than that, it's usually fat, and you'd want to take fuel out of it." This binder contains information about teaching using anchor charts as well as sample of anchor charts. On the other hand, high heat range plugs have short insulator legs and the surface area affected by the flame and the gas pocket capacity are small. Hotter plugs are listed above the colder plugs. It effectively adds timing by putting the spark closer to the piston, and it helps ignite the mixture. When more of the available fuel is burned, less fuel is wasted when the cylinder is vented during the exhaust stroke. Autolite AP5325-4PK Fuel Efficiency Platinum Spark Plugs, 4-Pack Overall Score: 9.0 10. Our unique DiamondFire ground electrode design has been modified to improve heat dissipation, and heat ranges will be available for numerous engine needs," says Steve. Racing Heat Range and Tuning Guide. Spark Plugs help remove heat from the combustion chamber. - Chris LaCouture. 0000006268 00000 n How is Heat Range Engineered? Alcohol, just plain alcohol, is very hard to see," Don adds. You want that tip to be about 1,600 degrees so it burns deposits off the tip, or else it fouls. LS1 Stock and AFR. Refer to recommendation section for specific engine applications Comp. The spark plug is heated during combustion and must dissipate that heat to the cylinder head at a certain rate to avoid overheating the ceramic firing end. You can check for the latest tips in our Tech Bulletins or Tech Videos sections. Although enthusiasts don't really care about fuel mileage or emissions, what if this same person said that swapping spark plugs could improve those metrics as well? 0000005364 00000 n Great value for money. Plug: NGK R5671A-10 (stock number 5820); Autolite AR3932; Champion C57CX (stock number 295); Denso IK-31 (stock number 5321) **NOTE: Use chart for static compression and adjust heat range for nitrous use accordingly. This results is less fuel being converted into energy, thus lowering combustion pressures," Steve explains. 0000014483 00000 n "Consistency of the spark is also greatly improved, which ensures a strong spark each and every cycle. All engines are not created equal, and carburetors can't meter fuel as precisely as EFI. Incorrect tools or crooked tools could crack the spark plug. Ideally, a pointed electrode would be the most efficient in flow but would quickly erode due to heat. Considering the lackadaisical approach most hot rodders take toward spark plug selection, what if someone came along and said you could increase horsepower and torque by 3 to 6 percent by simply swapping out the spark plugs? 0000031888 00000 n For many mild small-block aluminum heads, this spark plug would relate to an Autolite 3924 for street use. However, it does not impact its heat range. Thread - 14mm. You don't want to be the guy/gal stuck out on the water because of old plugs! . The structure of the spark plug affects the heat rating: Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. 0000011146 00000 n However, the barrel shaped connector can be unscrewed for installing ignition wires that used an eyelet connector, which is rare on today's street vehicles. 0000021292 00000 n Stock No. For example, with forced induction a "colder" spark plug should be used. The easiest vital sign to read is ignition. Reach, Projected Tip, Resistor . However, both provide an effective high-voltage electrical spark. 0000009247 00000 n High longevity and mileage. So if you can look at the plug as well as the oxygen sensor, you can get really close in your setup." Generally, in racing, you want them to run as clean as possible. It's quicker and CHEAPER than assuming the new plugs are good and the ignition coil is bad. It's definitely an intriguing proposition, and one that piqued our interest. Converting more fuel into energy equals better performance and fuel efficiency. Games and activities related to bar charts, line graphs and pie charts. And while the ground strap will fine-tune your ignition timing, you can also spot detonation early on the tip of the insulator: "As you start putting timing in the motor and you start to see a 'pepper' on the ceramic, little black specks, you're on the verge of detonation right there." - Chris LaCouture, E3 Spark Plugs Engineer Part# NGK STK # NGK # 44 3510 B6S 41-963 7740 PTR5C-13 45FFS 6222 BPR5HS 45 3210 B4 41-965 2467 PTR5A-13 45L 3112 B4L Don mentioned that when tuning an engine on the bleeding edge, like in a highly competitive drag-racing class, one or two specs are OK, but in a street motor, this is your first warning to stop and back off a few degrees. Consult the chart below for appropriate gaps for your model year. Because they transfer heat faster, cold spark plugs can get dirty and become fouled sooner because they dont get hot enough to burn off carbon deposits. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. Try to isolate it to one cylinder then check that plug first. The higher the number, the hotter the plug, and the lower the number, the colder the plug. If any of these components are damaged be sure to replace them or they may cause problems for your new plugs. If the plug is too hot, it can result in Pre-Ignition. The least intrusive is using a doctor's otoscope, that thing the doctor shoves into your ear drum every year. Also, since the heat release path from the insulator leg section to the housing is long, heat dispersal is low and the temperature of the center electrode rises easily. If you see any melting of any kind, that's a sign of pre-ignition. Post to Twitter or Facebook It appears that you have javascript disabled. If it's too cold, it can result in fouling and misfires. This research led to a multiple-edged tip that can lessen obstruction for flame propagation with a lesser mass of metal to reduce heat loss from the flame kernel. Reach, Projected Tip, Resistor, Each. ", Like many things that appear simple on the surface, spark plugs are far more sophisticated than most people realize. Spark plugs are made with ceramic, like the mugs in your kitchen. Old plugs can cause a loss of nearly 2-3 miles per gallon! "The 02 sensor will eventually lead foul and lead you astray, telling you the engine is leaner as it goes away, so you'll keep putting fuel in the motor. Learn more about quality spark plugs, find your part, or find where to buy your part today. This is a plug that sticks the spark farther into the combustion chamber, but higher cylinder pressures don't like that. Plug images are located on the opposite page. Worse yet, despite today's comprehensive engine management, the data is only as good as the tools used to read the fuel mixture: the oxygen sensor. I saw a show on hotrod tv, they did a feature on your E3 plugs. Likewise, older carbureted engines often have lower compression ratios, iron cylinder heads, and less efficient combustion chamber designs. But on the street, for driveability, you would want a power-tiptype spark plug. Do not drop the plugs on concrete! Now, the new E3 website is an inclusive portal for all spark plug applications as well as a technical center for information about our fuel-efficient line of premium performance OEM replacement plugs.

There has always been historical disagreement as to the inventor (Edward Berger versus Sir Oliver Lodge) and date that the first electric plug was used to spark the air/fuel mixture in an internal combustion piston engine. Ignoring the incompatibility with leaded race fuels (which foul 02 sensors) can lead to a miscalibrated or fouled sensor that can send you outside the envelope of safe tuning while whispering sweet stoichiometric nothings in your ear. "The unique DiamondFire ground electrode design has an open architecture that allows the flame front to expand toward the center of the cylinder, where the highest concentration of fuel is present. How long has it been since you've changed your spark plugs? E3 Sparkplugs TECHNICAL TIPS Getting the correct heat range when you purchase new performance plugs for your vehicle is critical! Within the Autolite family, this particular plug is toward the hotter side of the range that runs (cold-to-hot) 3922 - 3923 - 3924 - 3926. E3 says that the diamond-shaped straps on its plugs use the available voltage in the ignition system more efficiently. In these instances, a colder plug may be needed. Gap: Consult ignition mfg. 0000007777 00000 n When people talk about "reading a plug," they're most commonly talking about looking at the marks left behind by the burning fuel mixture on the insulator, where it radiuses out to the shell. 0000012941 00000 n "Heat range is determined by cylinder pressure or compression ratio of an engine. "A spark plug has two major functions for an internal combustion engine: It transfers heat from the cylinder to the head and ignites the air/fuel mixture," says Steve. How many pulls does it take you to start your edger/trimmer? This is usually the most misunderstood factor of reading plugs, because the fire ring is deep inside the plug and almost impossible to spot with the naked eye. Spark plugs with a high degree of heat dispersal are called high heat range (cold type) and those with a low degree of heat dispersal are called low heat range (hot type). 0000015209 00000 n Part# NGK STK # NGK # Comp. If you are running the Wordpress software, you will need the Embed Iframe plugin. Heat range is controlled by the length of the insulator nose. ", Unlike a traditional spark plug, the section of the strap above the electrode is open in an E3 plug. If you're getting ready to take out the lawn equipment for the first time this season and it's hard to start your mower or trimmer, it's probably time for a tune-up! ". 0000006304 00000 n To better understand the differences between various types, it is important to understand how a plug's design impacts engine performance, thoroughness of combustion and the durability of the spark plug itself including: Terminal - Opposite the threaded end of the plug is the terminal cap. Give your binder more style with rounded tabs by upgrading your account. 0000014456 00000 n Instead of a traditional J-strap, the E3 electrode is diamond shaped. Heat range. Nice to see a product that does what they say will do as a lot of products come and go -- your E3s went beyond what I ever expected. 78 0 obj <> endobj xref 78 49 0000000016 00000 n Welcome to E3 Spark Plugs online home to the advanced DiamondFIRE spark plug technology. Proper torque of your plugs can make or break your engine. However, the less amount of material near the gap the more rapid growth of flame kernels. Therefore, the insulation between the insulator and the housing falls, electricity leaks occurs, the spark across the gap is incomplete, causes ignition failures. Insulator - The central electrode that runs from the terminal connector to the base of the spark plug is surrounded by an aluminum oxide ceramic like the upper portion of the plug's shell but is not glazed. When you increase Compression Ratio or use boost, chamber temperature increases. This eliminates incorrect parts being installed. The early plugs relied on magneto-based ignition wires to provide the electrical flow that a plug requires to do its job. REASONS FOR CARBON FOULING: Continuous low speed driving/short trips; Spark plug heat range too cold; Air/fuel mixture too rich; Reduced compression and oil usage due to worn piston rings; Ignition system worn out. This can result in less burn, increased emission of unburned gases (or raw fuel), and reduced gas mileage. Manufacturer Heat Range. Since each application requires a different heat range of spark plug, a typical street-style spark plug usually won't cut it. I live in Canada and I put almost 100 miles on my car daily. The rest of the threads will be coated as the plug is screwed into the engine. Since they don't actually increase airflow into an engine, how much can spark plug design actually impact hp, torque, and fuel economy? Grease or dirt on the top of the spark can result in carbon track or flash-over. For most vehicles, it is best to use the manufacturer recommended plugs. Adding a more sophisticated ignition system will not be negatively impacted by the E3 plug," says Steve. For the majority of vehicles on the road today, an ignition coil rather than a magneto is used to amplify the voltage traveling through an engine's ignition wires. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The listed heat range represents the plug's ability to dissipate heat. 0000041768 00000 n You are $50.00 away from free US shipping. Iridium IX vs. OE Iridium Spark Plugs NGK builds two types of iridium spark plugs: OE Iridium and Iridium IX. Virtually all spark plugs use a copper-core center wrapped in nickel, platinum or iridium to conduct the electrical charge, jump the gap, and promote efficient heat dissipation. On the other hand, high heat range spark plugs have center electrode temperatures that do not rise easily, so they are unlikely to reach the pre-ignition temperature even at high speed. By focusing on improving the ignition cycles of the air-fuel mixture inside your engine's combustion chamber, our products are engineered to be environmentally friendly with a more complete and cleaner burn. E3.42 is a 14mm, 0.460 reach plug with a taper seat. All rights reserved. 3/4" Reach R5184-95 7485 291 IC 13/16" Hex R5184-10 7457 291 IC So [regarding] the heat range of the plug, you have to keep the plug hot enough to keep the tip clean, but cool enough that it doesn't cause detonation. Also since the heat release path from the insulator leg section to the housing is short, heat dispersal is high and the temperature of the center electrode does not rise easily. I love old musclecars but my everyday driver is a 2007 dodge caliber. Misfires, rough engine operation and headaches! "When the spark is weak or inconsistent, a smaller flame kernel is produced. This is a plug that sticks the spark farther into the combustion chamber, but higher cylinder pressures don't like that. Spark Plugs help remove heat from the combustion chamber. If the spark plug heat range is too hot, pre-ignition can occur. E3 spark plug heat range chart - motorcraft spark plug wire set - Web: http://www.autopartsstoresus.com/spark-plugs/spark-plugs.html This promotes larger, faster flame kernel growth and converts more fuel into useable energy.". Be sure that your spark plugs are torqued to meet your engines specifications. Our mission at E3 has always been reflected in our devotion to the advancements in ignition technology. According to E3, this offers several performance advantages. 0000439102 00000 n Tech resources for teachers, a la Bernajean Porter, 4th Grade ELA Common Core Writing - Range of Writing. "The improvements that E3 spark plugs provide tend to be more substantial and noticeable on older carbureted applications than newer EFI engines," says Steve.
