Professional™ Conventional Spark Plug by ACDelco®. Designed for today’s most popular autos, as well as several marine applications, ACDelco’s Rapidfire® Platinum Spark Plugs fit engines using conventional plugs, as well as newer vehicles requiring platinum performance.
- Ribless insulator that improves the plug-to-boot seal
- Tapered center wire electrode with a platinum pad reduces the firing diameter and helps improve the firing efficiency by concentrating and directing energy needed to fire the plug with less voltage
- Solid state suppressor with two-piece glass and brass seal helps reduce radio frequency interference, meters spark plug energy to help provide long electrode life and seals against compression leakage
- Reduced sparking voltage
- Greater corrosion protection
- Longer life and improved efficiency
