ACDelco RAPIDFIRE platinum spark plugs fit engines that require conventional or platinum plugs offering quicker throttle response, smoother idle, better corrosion protection, and greater longevity when compared to conventional plugs. RAPIDFIRE platinum spark plugs are available for most vehicle makes and models and several marine applications.
Product features:
* Ribbles insulator that improves the plug-to-boot seal
* Tapered and columned centre wire electrode with a platinum pad that reduces the firing diameter and helps improve the firing efficiency by concentrating and directing energy needed to fire the plug with less voltage
* A platinum centre electrode and platinum pad lower the ignition demand voltage and reduce possible flame kernel quenching
* One-piece integral suppressor seal helps reduce radio frequency interference, meters spark plug energy to prolong electrode life, and seals against compression leakage
* An expected life of 50,000 miles or better
* Gapped to the engine's original factory specifications
* 30-day, money-back guarantee and 3-year limited warranty
