Have a passion for racing? Autolite® racing spark plugs are engineered to deliver the action-packed performance that professional car drivers are looking for. Designed with a cut-back ground electrode, anti-corrosive nickel plating, and large ground electrode for better heat transfer, Autolite® racing spark plugs are the obvious choice for all types of professional drivers that are looking to reach maximum performance on the track.


Its cut-back ground electrode 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*
Its 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
*Testing performed by independent lab
