The E3.110 premium racing spark plug is a 12mm, 0.750-inch reach plug with a gasket seat built to have a cold heat range, non-resistor, and is used a variety of racing applications. This high performance spark plug features our patented DiamondFIRE ground electrode, which provides greater power, faster starts, better fuel efficiency, and lower emissions in long-term use. The electrode is secured to the shell with 2 legs to help facilitate heat transfer, and to withstand the intensity of high RPM racing engines. The edge to edge design provides increased efficiency and a faster, more complete burn, which make for optimal performance. The E3.110 spark plug is a replacement for CHAMPION plugs 905, 1005, A5YC, RA4HC, and RA4HCX, as well as Autolite AR4152 and AR4153.
E3 Spark Plugs racing spark plugs offer near-perfect combustion with their patented electrode design that allows for better growth. The DiamondFire design ensures that your vehicle runs at optimal performance, with a dramatic increase in power over an extended spark plug life.
