Poor idle, bad fuel efficiency, and engine misfire codes are all symptoms of worn spark plugs. Replace yours with these quality NGK iridium-tipped replacements to get your engine running smoothly again. These plugs are made with a platinum ground and iridium center electrode rather than copper.

Keep up on this maintenance item to avoid misfires which can cause damage to your catalytic converter. Worn plugs also make the ignition coils work harder which may cause them to fail.
