High Performance. Keeping your Mustang's high performance engine running smoothly and efficiently is important. You should routinely replace your old weak plugs with a new set of NGK Iridium IX Performance Spark Plugs for constant reliable spark power. The Iridium IX plugs from NGK will provide improved throttle response, fuel efficiency, lower emissions and will reduce fouling.

Superior Materials. NGK Iridium IX Performance Spark Plugs feature a copper core electrode for its superior conductivity and an iridium tip (which is 6X harder than platinum) for its extremely high melting point, perfect for keeping your Mustang's high-performance engine running at its peak. As an added bonus, the Iridium IX plug features Trivalent Metal Plating for its superior anti-corrosion and anti-seizing properties.

Application. This set of six (6) NGK Iridium IX Spark Plugs are specifically designed as a direct fit replacement for the 2005-2010 V6 and 1994-1997 V6 Mustangs.

gap What is the recommended gap for these spark plugs

galopinghorse

  • Read the sticker under your hood. Just about every car has one that tells you the spark plug gap size. If you are running a modified engine set up then the gap sizes can change and your performance part dealer should be able to advise you correctly.

Does anyone know if these plugs come pre-gapped. I remember the manual saying somewhere between 0.052 - 0.054 for the gap.

Santhus

  • These plugs will come pre-gapped to the stock specifications.

I am installing these spark plugs along with the screaming demon coil. I see many customers say to gap these at .065, does this make a real difference?

JoseM

  • Hey Jose, So these plugs will come pre-gapped for you and should pair well with the screamin demon coils. The more you gap it the more spark but you want to tailor the spark to the power of the car for the best results

I am running almost a stock setup. Only modification is CAI, Accel Coil Pack, and Taylor 8 mm live wires . As the heat range on these plugs are one step colder than stock will this plug hamper my engine and its performance. Seems like these are good match for highly modified engines ???

DIWAS

  • The NGK Iridium IX Performance Spark Plugs work well with stock and modified Mustangs. These will be a better match for a more highly modified car, but will not reduce the performance of your Mustang.

Is a tune required after installing these?

Nikobelic

  • The NGK Iridium IX Performance Spark Plugs do not require a tune, however, if you have a specific set-up that would benefit greatly, you could see a gain in efficiency with a tune.

    NGK Iridium Plugs

    I made the mistake of installing another brands "advanced technology" plugs that ran idle for a couple of months. Started to hear tapping slightly, Plugs (2) found unthreading from block. So, anyway purchased these NGK Iridium and the car now idles "quicker", quieter, and very smooth excelleration. I will now ONLY purchase these plugs. I have a couple thousand miles on them and I wont settle for anything less for now on. This is the ONE and ONLY 3.8 V6 recommendation I can guarantee a happy response after installing them.

    Good plugs

    The plugs, combined with 10mm LiveWires and GMS Coil, seemed to bring life to the 2010 V6 with 75k miles. Did give a quicker throttle response and a bit more pep to the non-ecoboost V6. My son is plenty happy with the increase in performance.

    Great upgrade

    After 161K miles with stock spark plugs, wires, and ignition coil, I decided to replace them and installed the NGK Iridium IX Performance Spark Plugs, Performance Distributors Livewires 10mm Spark Plug Wires, and the GMS Coil. Noticeable power increase of at least 20hp altogether and better gas mileage!

    adds kick to your Pony

    Make sue to use anti-seize compound, check gap to assure 0.050" if stock coil, up to 0.065" if using hi-po coil like screaming demon. The bigger/better the spark, the more "go" you get from your gas.

    Was Skeptical

    I had Bosch platimun's in before these and on the advice of Don from BAMA I installed these Iridium plugs... I didn't expect too much of a difference, but yeah, wow, I could definitely feel a better start and take-off from a standing stop... These plugs DO make a difference in our Stangs. Glad I got 'em... Recommend totally...

    NGK plugs

    Decided on these plugs along with the Screamin demon coil pack, Davis 10mm live wires and a Bama tune. Totally wakes the car up. A bit tricky to install, especially #3. However they totally are worth the money. My stang sounds great at an Idle. The NGK plugs do their job well. I would recommend this product to anyone.

    Best plugs ever!

    My 2008 "Warriors in Pink" stang has reached it's 100,000 mile mark and I knew it was time for a tune up. I read all the reviews and decided to go with the NGK Iridium IX plugs. I feel that this is the best decision I have ever made. Along with the Taylor Street Thunder 8mm plug wires and the Screamin Demon Coil pack, My stang has come back from the dead. My fuel milage has increased almost 4 mpg and she packs a punch on the throttle. Thank you American Muscle!!!

    Awesome felt right away

    very awesome just be careful you don't crack any start the install with your hand and inspect them before you install. cost is a bit high but they will last for a long time. Do one at a time and start your car(or better take a quick drive) after each to be sure they are all good this could help you from having to chase a bad one or a miss fire if one is bad.

    great spark plugs

    I installed these plugs with a set of msd wires and a screamin demon coil pak. As soon as I started my car, I could notice the idle was smoother and a bit quieter. I also notice a gain in gas milage while driving to work. These plugs are great for any mustang regardless of the amount of mods you have.
