Product Details

Chevron Up
Part No. AR472
Warranty Details (2 YR REPLACEMENT IF DEFECTIVE)
The ground electrode is cut-back from the center electrode to provide a gap. The face of the ground electrode is concave to provide a constant gap to the center electrode. This plug is designed use in all aftermarket cylinder heads used in different types of racing venues including oval and road racing.

Product Features:
  • Opens spark face for better ignitability of flame kernel
  • Retains less heat, transfers heat to shell faster - reduces risk of pre-ignition
  • Dyno testing has shown proven power gains
  • Cut-back ground electrode evolved from practice of grinding back the side electrode
