FAQ for Spark Plug Repair

Q: What should be noticed before installation?
A:
You will need to check the gap between all new and reconditioned spark plugs before installation. Pre-set gaps may have changed during handling. You can use a round wire feeler gauge to be sure of an accurate check, particularly on used plugs. Installing plugs with the wrong gap can cause poor engine performance and may even damage the engine.
