The Autolite Racing AR12 spark plug is built specifically for high-performance engines that demand maximum spark intensity and durability under extreme conditions. Unlike standard plugs, the racing series is designed to handle the high pressures and temperatures found in competition engines. These plugs provide the consistent ignition required for high-RPM performance, ensuring your engine fires reliably when you need it most.
The AR12 features a non-resistor design, which is preferred in many racing applications to ensure the strongest possible spark delivery without interference from internal resistance. The 0.460-inch reach and tapered seat provide a precise fit for specialized racing cylinder heads, ensuring that the electrode is perfectly positioned for optimal flame front development. Whether you are running on the drag strip or the track, these plugs are engineered to resist fouling and withstand the intense heat cycles of high-output engines. When every fraction of a second counts, trust the performance-proven design of Autolite Racing plugs to keep your engine running strong. Find all your high-performance racing components at GGCRACING.
