WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

To avoid possible damage to the tip, do not adjust the plug gap.
To prevent damage to the tip, use a wire-type plug gap gauge when inspecting the plug gap.

Measure the spark plug gap using the wire type plug gap gauge.
- If it is more than the maximum specification, replace the spark plug.
