ACCEL

ACCEL U-groove performance spark plugs produce a larger spark for more power at high RPMs. Improves throttle response and fuel economy, less fouling. Purified alumina insulator prevents arcing...

Made with a Copper Core Which is a Better Conductor than Platinum and Iridium. Delivers a Stronger Spark Especially in High Performance Application Where High Combustion Pressures Are Present. Copper...
