    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.

    Fitment: 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    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.

    Would these b ok to run with a nitrous set-up?

    • I would strongly recommend NGK's TR6's. They have a colder heat range which can more than support your application.

      NGK V-Power

      these plugs seam to work better then the ones that they put in this new motor, i set them at 45.5 before installing and the motor feels and sounds better , but being that i's a brandnew motor i can't really tell about gas mpg but i can say they are great so far. I would buy them again. Loneeagle

      '97 GT runs like new!

      Before I installed these plugs, my car had a rough idle and it got bobbed down in lower RPMs. I put the plugs in and they solved both issues. I can definitely feel the increase in power and responsiveness! I would 100 recommend these plugs. Just a tip about the install. I just used a deep socket with a jointed extension to loosen the old plugs, and I used a bent metal clothes hanger to get them out and place the new ones in. I just mention that in case anyone else is cheap like me and doesn't want to buy the spark plug tool.

      90k service

      My original motorcraft plugs were really struggling when my car finally hit 90k miles the only thing was I didn't realize you have to pull the fuel rail out to access the plugs on the passenger side just a warning its not the most fun and after the plugs were in it seemed to gain a few hp but that could just be a placebo effect but it was a needed service

      Perfect replacement.

      These spark plugs were a replacement to my original ones that started going bad. No more rough idling, no more hesitation, no more CEL and my scan tool shows no errors, I'm a happy camper. The price for these were just right and I will buy in future.

      Fits perfectly, only had to regap 2 or 3 of them. Got rid of some rough idling. Easy fix. Make sure you put some anti seize on them before! Looks like the ones before did not have it done.

      Nice spark plugs

      As you well know the 4.6 Romeo engine kind of needs plug every 30 to 40 thousand miles.. I rather not take him out and clean them I'd rather just replace them
