Autolite - Racing Plug

The Autolite Racing Plug is engineered for high-performance racing applications, featuring a yttrium-enhanced alloy that reduces sidewire temperatures by up to 8%, enabling performance modifications and handling intense conditions. Its cut-back ground electrode ensures better ignitability of the flame kernel, leading to quicker starts. The anti-corrosive nickel plating prevents rusting more effectively than black oxide, enhancing durability. Designed with a high alumina multi-rib ceramic insulator, it provides superior thermal conductivity and insulation, preventing flash-over. This non-resistor spark plug is ideal for professional racers seeking maximum engine performance on the track.
