Description

ABOUT THIS PRODUCT

Autolite Racing spark plugs are meticulously crafted to elevate engine performance under demanding conditions. Featuring a cut-back ground electrode, these plugs optimize ignitability and enhance heat transfer for quicker starts and consistent power delivery. The yttrium-enhanced alloy reduces ground wire temperature by up to 8%, making them ideal for colder heat ranges and performance modifications. Built with anti-corrosive nickel plating, they resist rust better than black oxide, ensuring long-lasting durability and efficiency. The high alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation, preventing flash-over while increasing strength. Designed with a short projection nickel center electrode and tapered seat type, these performance-grade spark plugs are tailored for racing applications, delivering reliability and precision on the track.

Product Features:
  • Engineered with a cut-back ground electrode that delivers optimal ignitability of the flame kernel and better heat transfer, leading to quicker starts.
  • 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.
  • Designed with an anti-corrosive nickel-plating prevents rusting better than black oxide, allowing the plug to maintain its durability and efficiency.
  • Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength while preventing flash-over.
