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.

As an added bonus, the Iridium IX plug features Trivalent Metal Plating for its superior anti-corrosion and anti-seizing properties.

  • These plugs should prove to be good performers. You should get good burn without problems. They are high quality plugs made to work in extreme conditions.

Witch spark plugs wires are recommended for these ?? any names. And will I really get more MPG with these and the demon coil ??

Sally

  • Any of the plug wires AM sells are good high performance wires. It honestly depends on the customer. I have found the Ford 9mm wires are very good, plus the Taylor wires have proven to work well on the wife's Mustang. I am partial to the Accel wires as well. Although I know the NGK plugs are of good quality and should improve performance, I think you'll find the E3 or Bosch Plus4 plugs to offer the overall best performance and gas mileage increase. Sorry AM, I know you don't carry the Plus4 plug, but I think you should.

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.

Is it necessary to use anti seize and dielectric grease on these? I have heard anti seize compound on the threads and dielectric grease on the electrode is a good idea. Is it really necessary to use these products on these plugs?

Ridethepony1963

  • It isn't necessary, per se, but it is recommended. The anti-seize on the threads will keep the plug from galling or seizing in the head and make them easier to service in the future. The dielectric grease will help keep dirt and water/moisture out which help deter moisture intrusion, or corrosion, that can cause misfires. Both are inexpensive insurance to make sure that future tune-ups are easier and more straight forward.

    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.

    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.

    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.

    I installed this plugs and right as soon as I turned the car on I could here and feel a difference. Also in the first week of having them in i noticed a little gain in mileage too. A must have part even just for maintenance.

    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.

    Great Plugs!

    Decided to do a tune up on the Lime so I decided to upgrade to these spark plugs. Great quality and I highly recommend these. Car idles nice now since I changed to these plugs and did the Taylor spark plug wires and upgraded the coil to the Screamin Demon.

    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...

    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.

    Easy to install. Noticed a much smoother operation(old plugs were 47k old). Along with the thunder wires this took about an hour to install. Would have been quicker, but the demon coil I purchased was defective. Good old AM was on top of it though and a new one is already on its way to me.
