1972-1975 Corvette SF14E SplitFire Spark Plugs For 350ci/454ci

There's nothing hotter on the market than SplitFire spark plugs. A quick comparison shows how this new design clearly distinguishes it from other plugs. SplitFire's open split on the ground electrode better exposes the spark to the incoming air/fuel mixture. In addition, the spark is larger than those of a conventional plug. The spark not only travels sideways, but also can travel upward through the v-notch into the combustion chamber. Experts say the result is improved combustion of the air/fuel mixture as seen in better power, mileage and reduced emissions. Set of eight.
