Technical specifications

Installation requirements

Work on a cold engine and remove one lead or coil at a time to avoid mixing up the firing order. Clean around each plug hole, thread the new plug in by hand and torque to specification. Iridium tips are fine and can be damaged by gap tools, so avoid adjusting unless your manual requires it. Fit a full matched set for even running.

Fitment checks before ordering

GM engines in this range use plugs with different seat types and reach. Compare the number on your existing plugs or in your owner's manual, and confirm by engine code or VIN before ordering. Contact us with your engine details and we can help confirm the right plug.

Many of these vehicles are imported into New Zealand, so checking the engine code rather than the model name gives the most reliable result.
