AUTOLITE 458 Part Description
Manufacturer
Features & Benefits
- Nickel-coated electrodes help reduce metal wear during repeated combustion cycles
- Solid-core internal makeup promotes signal strength for high-output coil packs
- Extended insulator shape helps discourage fouling during low-speed trail crawling
- Heat range selection suits engines facing fluctuating airflow during off-road inclines
- Shell integrity supports gasket sealing in engines exposed to dust-heavy environments
Autolite Copper Non-Resistor Spark Plug
The Autolite Copper Non-Resistor Spark Plug supports older ignition systems found in vintage off-road rigs that undergo frequent throttle bursts on rugged trails. Its copper core moves heat away from the firing tip, helping retain cleaner operation when engines cycle rapidly between low-crawl torque and sudden acceleration. The 13/16-inch hex provides tool access for vehicles with narrow plug wells shaped by older casting designs. Its non-resistor configuration sends a stronger signal across the gap, which benefits engines tuned for dense fuel mixtures during steep climbs. The Autolite 458 offers spark stability for platforms where ignition energy is prioritized over electronic noise control.
