Experience reliable ignition and peak engine performance with the Autolite Copper Spark Plug 4345. Designed with a full copper core electrode, this spark plug ensures consistent spark delivery for smoother starts, improved fuel efficiency and dependable power in all conditions. Its copper-glass seal bonds the insulator and terminal post together, creating a 100% gas-tight seal that delivers the full required voltage at the spark gap, while the multi-rib insulator reduces the risk of flash-over for safer, more efficient operation.
Built for durability, the Autolite 4345 features a one-piece terminal post for added strength, a cold-formed steel shell with precision-rolled threads and a built-in resistor to minimize radio frequency interference (RFI) and electrode wear. Perfect for routine maintenance or performance upgrades, this spark plug provides the combination of reliability, longevity and superior ignition power every engine needs. Always verify cross-reference listings before purchase to ensure proper fit.
