• Hard starting or rough idling conditions
• Excessive electrode wear reducing spark quality

Installation Notes and Tips

Ensure the spark plug gap is set to the specified pre-gap size of 0.044 inches (1.10 mm) before installation. Use a 5/8 inch (16 mm) socket wrench for proper tightening to avoid damage to the tapered seat. Confirm thread diameter compatibility (14.0 mm) and reach (0.431 inch / 11.0 mm) with your vehicle’s engine specifications. Avoid over-tightening to prevent thread damage. It is recommended to replace spark plugs in sets to maintain balanced engine performance.
