ACDelco RAPIDFIRE Performance Platinum Spark Plugs

ACDelco's RAPIDFIRE platinum spark plugs fit engines that require conventional or platinum plugs, offering quicker throttle response, smoother idle, greater corrosion protection, and greater longevity when compared to conventional spark plugs. The RAPIDFIRE platinum spark plugs are available for most vehicle makes and models and several marine applications.

Features include:

* Ribless insulator that improves the plug-to-boot seal
* Tapered and columned center 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 center electrode and platinum pad lower the ignition demand voltage and reduce possible flame kernel quenching
* One-piece integral suppressor seal that helps reduce radio frequency interference, meters spark plug energy to help provide long electrode life, and seals against compression leakage
* An expected life of 50,000 miles or better
* Gapped to the engine's original vehicle manufacturer's specifications
* 30-day, money-back guarantee and 3-year limited warranty
