ACDelco's RAPIDFIRE Performance Platinum Spark Plugs offer longer life and improved efficiency over time as compared to conventional spark plugs.
Available for most vehicle makes and models, and several marine applications, the RAPIDFIRE Platinum Spark Plug design features:
- Rib-less insulator that may improve the plug-to-boot seal
- Tapered 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
Show More
- 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
When compared to conventional spark plugs:
- Reduced sparking voltage
- Greater corrosion protection
- Fits engines that run conventional plugs, as well as newer vehicles that require platinum plugs
