Autolite Copper Non-Resistor Spark Plug
The Autolite Copper Non-Resistor Spark Plug helps owners of classic performance engines and race-prepped combinations that use simple ignition systems and do not require radio-noise suppression. Its non-resistor layout allows more of the ignition coil energy to reach the gap, which can benefit engines running rich mixtures or higher compression ratios at the track. The 13/16-inch hex format suits many older cylinder heads, giving tuners easy access when swapping heat ranges or checking plug color between passes. Copper conduction aids heat movement away from the firing tip during extended high-RPM operation. The Autolite 456 gives builders and racers a plug choice for vehicles where ignition strength matters more than electronic interference control.
