Buying Guide On Best Quality Spark Plugs
1. Understand Your Vehicle’s Spark Plug Requirements
Check the owner’s manual for spark plug size and type. Different engines need specific plugs. Using the wrong one can cause poor performance. Match the heat range to your engine’s needs. This ensures the plug works well and lasts longer.
