The Blue Point three-valve Ford Triton Insert Kit, No. FRT12, is designed to aid in the repair of three-valve 5.4L and 6.8L engines built before Oct. 9, 2007, and three-valve 4.6L engines built before Nov. 30, 2007, found in many 2004–2008 Ford, Lincoln and Mercury vehicles. In above models, the spark plug tends to break off in the cylinder head during maintenance. If this problem is not repaired properly, it can result in damaged or unusable spark plug threads, or a spark plug blow out. This kit will allow the user to repair those damaged threads or blowouts in 30 minutes or less per cylinder.
