      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 1993-2001 SVT Cobra, 2003-2004 Mach 1, 1996-2004 GT/Bullitt and the 1998-2004 V6 Mustangs.

        5 2001 GT - 1slow2v Installation Time: Afternoon

        Worked Great

        Was having a rough idle and I replaced my spark plugs, and since the problem has been solved. It took me an afternoon but I’m not very car savvy so that’s why

      Does this come with any gap tools, or just the spark plugs?

      • The NGK V-Power Performance Spark Plugs will no come with a gap tool as they are "Pre-Gapped" in the box.

      Is there really any difference between these and let's say a higher priced kind?

      • These NGK V-Power Performance Spark Plugs have a copper core with a nickel tip. The more expensive ones have platinum or iridium tips, which generally last longer.
