Vehicle Fitment Guide

Notes:

• You can contact us if you are unsure about fitment.
• Gap the new spark plugs as recommended in the above fitment guide or car owner's manual. Use a feeler gauge to measure the gap between the center and ground electrode. The gauge should pass through snugly but easily. If too loose or too tight, reset the gap.
