SPARK PLUG CHECK AND CLEANING <6G72 without catalytic converter>

<Tri-electrode plug>

note

As the prospective distance for this spark plug replacement, 100,000 km is for the with semi surface discharge. Unless the plug is remarkably burned or worn, and the insulator plug is damaged, adjust the plug gap and check the plug state. Clean the plug if necessary.

1.Check that the plug is not burned, that the insulator plug is not damaged, and that the seizure state is good.

2.If cleaning is required due to carbon deposits, etc., clean using a plug cleaner or wire brush, etc.

3.Check the plug gap using a plug gap gauge, and adjust if not within the standard value.
