Fitting Tips
Always replace spark plugs as a complete engine set. Check the electrode gap before installation, thread the plug in by hand to avoid cross-threading, and torque it to the engine manufacturer’s specification. Over-tightening damages the thread and under-tightening causes poor heat transfer. A fresh set restores smooth idling, easy starting and fuel economy.
