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.

Available for most vehicle makes and models, and several marine applications, the RAPIDFIRE Platinum Spark Plug design features:

• Ribless 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
• 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
• Gapped to the engine’s original vehicle manufacturer’s specifications
• Thirty-day, money-back guarantee and three-year limited warranty
