Auto · Spark Plugs

How do I know which spark plug fits my vehicle?

Reviewer consensus

Fitment is everything with spark plugs. Match the exact OEM part number or use a verified fitment lookup for your year, make, model, and engine before buying. Several of these listings are vehicle-specific (Harley Twin Cam, Ford 4.6L/5.4L V8, Nissan 3.5L, Hyundai/Kia 2.4L), so confirm the cross-reference rather than relying on the heat range alone.
