[QUOTE="swshawaii, post: 1004165, member: 67547"] Ditto Eddie, the factory recommended interval is 100K. Primary concern is the OEM plugs could seize in the aluminum heads. You may also find the drivers side electrodes worn with gaps that are much wider than the .054 spec. Use OEM Motorcraft SP500, Autolite APP103 or XP103 plugs for proven results. Antiseize and dielectric grease optional for another 100K. [b][Broken External Image][/b]: Screechy removal at 61K, exactly HALF your mileage. Only Chevron 87 octane regular or E10 fuel used.
