Spark Plugs for supported vehicles
Spark plugs must match the petrol engine, heat range and vehicle application. Vehicle Search and OEM references are useful starting points. Use the vehicle application and current catalog result to check availability.
Choosing spark plugs
What the part does
Spark plugs provide the ignition point for petrol engines. Reach, heat range, electrode design and engine application all matter, so a plug that looks similar may still be unsuitable.
How to identify the right application
Confirm the petrol engine code or complete vehicle record and compare the returned article number. Diesel vehicles require a different ignition-component discussion.
Replacement and purchasing considerations
Misfire, difficult starting, uneven idle or changed fuel consumption justify inspection, but symptoms do not prove one plug reference. Keep the removed reference for comparison and follow the vehicle-specific service guidance.
Use Vehicle Search when the vehicle is known, or use OEM Search when a reliable reference is available. Browse a related guide: Spark Plugs.
