Keep every cylinder firing cleanly with the Champion Spark Plug 322-1, a direct-fit replacement plug for a wide range of listed applications — from the 1965 Chevrolet Bel Air, Biscayne, Chevelle and Corvette to Chrysler, Dodge, Mitsubishi, Nissan and Hyundai models. It delivers the spark that ignites the air-fuel mixture in the combustion chamber, one of the small components a healthy running engine depends on.
- Ignition source: fires across the electrode gap to light the air-fuel mixture on each combustion stroke.
- Direct-fit replacement: installs as a straightforward service replacement on the 102 listed applications.
- Broad coverage: one plug spans decades of makes and models across the Buyer's Guide list.
Spark plugs are a wear item. If you notice rough idle, engine misfires, hard starting or reduced fuel economy, worn plugs may be a contributing factor — but these symptoms can have other causes, so diagnose the condition before replacing. Engines use one plug per cylinder; replacing the complete set together helps keep ignition even.
