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

Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 1Your engine having trouble starting, hesitating, or cutting out
Faq - Answer 8Yes, ACDelco has marine spark plugs for many applications.
Number Of DoorsVarious Application Specific
Signs Of Wear &#38; Troubleshooting - Section 1 - HeaderSigns of wear for spark plugs include but are not limited to:
Faq - Answer 7No, cleaning your old spark plugs is not recommended. Dirty, fouled spark plugs may also have broken or chipped insulator tips, worn electrodes, or worn or missing side wires. These conditions severely affect spark plug performance. Replace your dirty, fouled spark plugs with new ACDelco spark plugs.
Faq - Answer 6Yes, pre-ignition can cause serious damage to your engine. Pre-ignition is the ignition of fuel before the actual spark occurs, which causes a rapid temperature rise in the combustion chamber that can damage engine components and melt spark plug electrodes. Causes of pre-ignition include but are not limited to a buildup of deposits that can become incandescent in the combustion chamber, improper installation torque being applied to spark plugs, and having spark plugs with a heat range that is too hot for the engine's operating condition.
Faq - Answer 5Not always, but you should inspect your spark plug wires for wear when replacing your spark plugs. Refer to your vehicle owner's manual or contact the manufacturer for more information.
Faq - Answer 4Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification.
Faq - Answer 3Yes. Diesel engines require glow plugs because diesel engines operate differently than gas engines. ACDelco Professional Glow Plugs are specially designed to give diesel engines the heat they need for their cold starts. Contact your local dealer, ACDelco service center, or refer the manufacture’s service information.
Faq - Answer 2Yes, if it is the scheduled time for spark plug replacement.
Faq - Answer 1Yes, this interval depends on what type of spark plug your vehicle requires. Refer to your owner's manual or contact your vehicle's manufacturer for more information.
