Designed for today's most popular autos, as well as several marine applications, ACDelco's Rapidfire Platinum Spark Plug fits engines using conventional plugs, as well as newer vehicles requiring amazing and platinum-grade performance.

Features

• 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
• One-piece integral suppressor seal 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
• Longer life and improved efficiency over conventional plugs
