A reference, not a fitment guarantee.

Always confirm thread size, reach, seat type, heat range, and gap against the engine manufacturer’s recommendations before fitting a replacement.

What to Check Before Choosing a Replacement

Use the recorded dimensions as a starting point, not as a fitment guarantee.

Dimensions and Seat Type

Compare thread diameter, reach and seat type with the engine manufacturer's requirements. Similar-looking plugs can have different dimensions or seats.

Heat Range, Gap and Engine Application

A cross-reference match alone does not confirm heat range, electrode gap or engine application. Check the manufacturer's application catalogue and installation guidance before fitting another part number.
