    Increased Power. Replace your Mustang GT's old tired coil packs with better performance versions. SR Performance's 42,000-volt coils provide 22,000 more volts than the weaker factory coils to produce more power and torque out of your 5.0L engine. The 4V Coil Pack Kit is an ideal replacement upgrade for stock or lightly modded GTs in need of an additional power boost.

    Better Fuel Economy. These SR Performance Coil Packs not only improve the rear wheel power of your GT, but they also improve its fuel economy as well. Because of the higher voltage of these Coils your spark plugs will produce a hotter spark. A hotter spark burns the air/fuel mixture more completely releasing all of it's potential energy which translates into better fuel economy and more power that you can feel in the seat of your pants.

    0 OHM Technology. These SR Performance Coil Packs feature 0 OHM technology. Manufactured with a silicone magnetic steel core that has 0 OHMs of resistance, these Coils allow all the spark energy to transfer to the spark plugs. This design not only improves spark power, but it also suppresses Radio Frequency Interference (RFI) and Electro Magnetic Interference (EMI) to effectively shield your GT's sensitive electronic components from interference.

    Complete Kit. This SR Performance Coil On Plug Kit comes complete. The Kit includes the 8 coil packs with connector cables, and stainless snap lock plug connectors.

    Application. This set of eight SR Performance 4-Valve Coil Packs are designed as a direct fit performance upgrade for the 2011-2016 Ford Mustang GTs equipped with the 5.0L engine that were built before 2/23/2016.

        Questions...Spark plugs. -With the SR coil will stock plugs be OK, or should I replace them with a colder plug? -There was a question with an answer from someone else in regards to plug gap..The answer was ( however to get the maximum performance gains, the spark plug gap should be slightly opened up )....What is slightly opened up??? -With these coils will spark plug life be reduced? Thanks, John

        • The SR Performance 4V Coil Pack Kit can be used with stock plugs, a colder heat range would only be needed for applications that are making enough power to require the colder heat range. Spark plug gap will vary with every individual setup, dependent on performance parts installed, quality of fuel used, tune, etc. Some experimentation may be required in order to achieve the best performance. Spark plug life should not see any significant reduction in lifespan with these or other aftermarket coils due to the robust nature of modern spark plugs.

        Will they work with a ROUSH stage 2 supercharger? 2015 gt?

        Are these cool packs compatible with the msd 2step wiring stuff?

        Would these coils affect air fuel ratios to where it would run lean decelerating?

        • Thes coils would not have an effect on the air-fuel ratio.

            Very easy, look good

            It was a nice install, super easy. I don't know about throttle response, but it smoothed out the idle enough when I backed out, I thought the engine had died. Would definitely recommend. Haven't had them long enough to comment on longetivity, but they seem just as good as oem coils.

            I was not expecting such a big difference. I recently had started driving most of the time in sport mode, I thought I had just become bored with it. I replaced the plugs along with the coil packs and wow!! bonus 1.5mpg back to driving in normal mode again.

            So far so good.

            Heard both good and bad about aftermarket coils. Nothing really earth shattering but maybe a little cleaner idle. We will see if they last.

            Coil Packs - Worth the cost!

            I reviewed the available coil packs prior to purchasing the SR Performance set from AM and am very pleased with the product. My wife and took our time and installed these, and a new set of NGK Laser Iridium spark plugs, in about 90 minutes. Prior, our pony was “missing’ occasionally when under a higher rpm sustained pull. The SCT tuner read the code as multiple misfire. Since the install we have not experienced the misfire and the pony seems more responsive. For reviewers benefit we have; Airaid cold air intake with 91 octane Bama race tune, Roush axlebacks, SR Performance F/R lowering springs and F/R sway bars, Koni yellow F/R adjustables and Hurst short throw stick. Running BF Goodrich comp 2 275s on all corners. Presently at 162K and running fantastic! Additionally, decided to perform a MPG check using the vehicle program. It was the best we have seen at 31 MPG running 75-80 MPH for 35 minutes.

            Go with a different brand

            Purchased in Dec 2017 installed in the following January. Got under a year and a half of in my daily driver 5.0 and one of them crapped out on me, outside of the year warranty of course. Do your research and go with a more trusted brand with a better warranty.

            Worth the price tag

            Recently purchased these and some NGK Iridiums before my dynotune, and honestly felt a difference. Idle was smooth as could be, Plugs gapped @ 50, minor bolt ons “JLT intake, Roush ABs and SCT 93 Custom Tune”, my cr has 127xxx on it, an laid down 401whp 402tq. These allowed me to get there, would defiantly recommend getting if your changing the plugs anyway, took 1 HR and I’m meticulous.

            Good over all, work alot better than the stock ones when running boost, but i had one go bad pretty much exactly a year after install and there's only a 30 day warranty and you cannot purchase individually its a set of 8 kind of deal.

            Wake up call

            The stang has seemed to be not living up to the kids already made. Once I installed the new oil packs and the NGK plugs ,, it woke the Grinch up. Noticed the instant gains the extra 20,000 volts have me. Only drive a short while to make sure everything worked like it should. Would recommend this upgrade to anyone. Install was easy, only basic tools were needed. AM is great, right parts the first time everytime. Got the parts 2 days earlier than delivery date stated. The Grinch and I are both happy.

            Very good, reliable product. Easy to install. Plug, and play! I'd definitely buy them again. It's my 1st set.I have a 2012, and the factory one's lasted 7 years. I suggest having a magnet if you're changing out the plugs like I did! The hardest part was unplugging the coil packs.
