E3.22 spark plug cross reference7/27/2023 Typically white in color, the shell may or may not include ribs but usually includes a brand name, logo or set of identifying numbers printed on the outer surface. The shell is a ceramic outer casing that is fitted into the threaded metal housing at the end of the plug where the ground electrode is found. Shell - For most people, the shell is the most obvious feature of the traditional spark plug. 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. For most cars and trucks, the rubber boot at the end of each ignition wire can be firmly pushed over the terminal's barrel-like tip. Terminal - Opposite the threaded end of the plug is the terminal cap. 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: There are numerous spark plug designs available from online vendors, big discount stores and auto parts dealers. You can read more about ignition theory and combustion cycle analysis in the Technology section of this website. This is where E3's DiamondFire technology helps to reduce the amount of unburned gases emitted into the environment when the exhaust valves are open. At the end of the spark event, a small flame kernel remains as raw gases continue to burn. Once the voltage created by a magneto or ignition coil exceeds the dielectric strength of the gases in the motor's combustion chamber, an explosion occurs and the piston is send downward completing a cycle. However, both provide an effective high-voltage electrical spark. 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. The early plugs relied on magneto-based ignition wires to provide the electrical flow that a plug requires to do its job. Among the early engineers seeking protection for their ideas was Nikola Tesla for his ignition timing system. Patent office began issuing patents to protect a variety of ignition products in the late 1800s. 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.

If you are a returning E3 visitor, let us know how you like the changes to our website. home to the advanced DiamondFIRE spark plug technology. Make sure and read the part about how detonation makes the plug look cleaner.Welcome to E3 Spark Plugs online. How you can read spark plugs and select them - by Gordon Jennings (Note: Geared towards Motorcycles but very good info here.Another excellent "How to read Spark Plugs" article.Spark Plug Reading Discussion going on in our message board.Champion Heat Ranges - Typically Champion numbers in the same series the larger the number the hotter the plug.Example a AR3935 (good street/strip plug) is hotter than a AR3932 plug which is very cold used for lots of nitrous. Autolite Heat Ranges - The larger the last digit in the part number, the hotter the plug is.Example a R5671A-7 (a good street/strip plug) is a cold plug where a R5671A-10 is a very cold plug used for large 400hp and up nitrous and other power adder applications) NGK Heat Ranges - The larger the number after the dash the colder the plug is.
