Description
Regular Maintenance. Replacing your old weak spark plugs is paramount to keep your engine running smoothly and efficiently, so why replace them with the same old sub-par stock plugs when performance V-Power plugs from NGK will improve fuel efficiency and lower your emissions.

Superior Design. NGK V-Power Performance Spark Plugs feature a copper core for its superior conductivity and a durable nickel alloy tip to assure a strong spark to keep your stang running at it's peak efficiency. The V-Power plug features a unique V-Groove that allows the spark to happen at the edge of the center electrode, so that the heat is not absorbed by the electrode itself, resulting in a complete efficient burn.

Application. This set of eight (8) NGK V-Power Performance Spark Plugs are specifically designed as a direct fit replacement for the 2003-2004 SVT Cobra and the 2007-2014 Shelby GT500 Mustangs.

Q & A Ask a Question

Will these plugs work for a 2004 Mach 1 on 100 shot of nitrous? Are they cold enough, my car just has the basic CAI and exhaust. I want a good nitrous plug.

    New Plugs

    I replaced the stock 2007 plugs with the NGKs. The install was easy, after removing the CAI. Haven't had a chance to drive the car much, but I'm looking forward to hitting the streets when the temps go up.

    Adding boost get these

    I added a 10% pulley and a 2.6 pulley on my 08 gt500 (building over 15 psi of boost) and didn't change plugs. The car would lose power, misfire, and detention was taking place at WOT. Ordered these plugs, they showed up the next day. Install was easy just be sure the gap there correctly and add some anti-seize for good measure. The plug change fixed all the problems stated above. Great product and great delivery time
