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.

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

Mike

  • 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?

Zacb911

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

    NGK COPPER CORE PLUG

    These are by far the greatest plugs made for any street car. They diffinitely improve gas mileage, performance and all around comfort in your engines overall performance and response to these high energy conducting plugs. Don't get sold on the Iridium/Platinum gimics. I learned the hard way spending over $300 on those types of plugs just to learn that they don't do as they advertise. There's a difference between testing in a facility and realy world use. Go with NGK V-Power and you won't go wrong. 98 Saleen S351 Out.

    These spark plugs work great. They make the car idle better, feel more confident, and put the rumble back into your exaust. Performance gains are really unnoticalbe, but this is not a mod to gain more horses... Make sure you gap them .054 and you'll be all set. Also, you can install with out removing the fuel rails, just need to get creative with extentions on your ratchet.

    NGK V-Power Plugs

    This plugs are exceptional. They brought the pep back to my '96 Cobra. It was a relatively easy installation for a backyard mechanic, as myself. If you review any motorsports mags, you will find NGK recommended 95 percent of the time over other national brands. Purchase! You will NOT be disappointed! Layton, UT

    Yet again, NGK is where it's at!!!!

    I gapped my plugs to .054 and installed with my MSD coil and Taylor Spiro 8mm plug wires....WOW!!!! My car idles as smooth as silk, my exhaust note is deeper, there is ZERO lag when shifting from first to second and the performance gain that came with all of the above parts really made a difference with my A.M.

    NGK V-Power Spark Plugs

    My 98 v6 had factory plugs and wires still with 117k miles on them. Started having misfires so it was time for new ones. These went in great, and were a good fix from the 18 year old factory plugs. These made my engine run so much smoother and no more misfires. Thanks to AM for fast and free shipping too.
