Mustang NGK TR55 Spark Plug Kit

Replace the fouled spark plugs in your 1996-2004 Mustang with this NGK TR55 spark plug kit! Featuring NGK's V-Groove technology, these spark plugs increase ignitability to improve performance and fuel mileage! Their V-Groove allows the spark to materialize at the edge of the center electrode. This means the heat is not absorbed by the electrode itself to allow the flame to expand quickly and efficiently! The copper core provides better heat removal while the ceramic insulator provides superior strength and heat transfer. This kit includes 8 spark plugs to overhaul your ignition!

The original factory spark plugs in the 1996-2004 GT, Mach 1 and Cobra applications listed below were platinum plugs, however, the copper plugs in this kit will fit and work great as a suitable replacement. Be advised that copper and nickel plugs will have a shorter service interval than the platinum plugs.
