Product Details
Part No. AR135
Warranty Details (2 Year Warranty)
Autolite Racing spark plugs are precision-engineered to elevate your engine's performance on the track. Featuring a cut-back ground electrode, these plugs ensure optimal ignitability and superior 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 under intense racing conditions. With anti-corrosive nickel plating, these plugs resist rust better than black oxide, ensuring long-lasting durability and efficiency. The high alumina multi-rib ceramic insulator provides exceptional thermal conductivity and insulation, preventing flash-over while enhancing strength. Designed with a tapered seat type, these spark plugs deliver peak performance in demanding oval and road racing applications. Built for durability and reliability, Autolite Racing spark plugs are the ultimate choice for racers seeking maximum engine output and resilience under pressure.

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.
  • Optimal Performance: Features a tapered seat type, ensuring optimal performance in intense racing conditions.
  • Durable Design: Engineered to handle intense conditions, this spark plug is perfect for both oval and road racing applications.

Black Friday can't beat this deal
I have used this product in all my blown & injected alky burning sbc engines with great success from reliability,performance and longevity. I have also started to use this product in a triple turbocharged alky burning tractor puller that i help work on that belongs to a friend of mine that we had some problems with other brands before. they seem to hold up better since we changed over to a pro mag 44 ignition.
