Description:
Autolite Racing spark plugs are engineered with a cut-back ground electrode, anti-corrosive nickel plating, and large ground electrode that deliver better heat transfer, ensuring maximum engine performance on the track.
Features and Benefits:
- Designed with an anti-corrosive nickel-plating prevents rusting better than black oxide, allowing the plug to maintain its durability and efficiency.
- Engineered with a cut-back ground electrode that delivers optimal ignitability of the flame kernel and better heat transfer, leading to quicker starts.
- Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength while preventing flash-over.
- The yttrium-enhanced alloy enables up to 8% reduction in ground wire temperature for colder heat ranges designed to enable performance modifications and handle intense conditions.
