    Power and Performance. If it's time to replace your Coyote powered Mustang's old, worn out coil packs don't settle for factory replacements, upgrade with a set from SR Performance. This SR Performance 4V Coil Pack Kit is rated at 42,000-volts, that is 22,000 more volts than the stock coils, for improved power and performance. After installation you will see an increase in power, better throttle response and a noticeably smoother idle. SR Performance 4V Coils are an excellent replacement upgrade for stock or lightly modded 5.0-liter Mustangs searching for 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.

    No Tune Required. These Coil Packs are designed to improve the performance of your Mustang without the need of reprogramming your computer. The engineers at SR Performance really did their homework to improve your Mustang's power using the factory tune.

    Not CARB Certified. These Coil Packs are not CARB certified at this time, therefore they are not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    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 2016.5 to 2017 Ford Mustang GT models equipped with the 5.0L engine that were built after 2/23/2016.

    Would these be more beneficial with a tune?

    • You will definitely see better performance when combined with a tune. With that being said, a tune is not required.

    Would it be a good idea to upgrade the spark plugs when installing these when I already have multiple bolt on upgrades(CAI, Throttle body and spacer, exhaust and x pipe, MAF sensor) and a bama tune? If so which spark plugs would you suggest?

    • Unless you are running Nitrous or you have a forced induction set up it is best to run the OEM plugs.

      Smooth idle

      Due to winter conditions I have only been able to take my car on a short drive but it feels strong even with little traction with cold tires.

      Every little bit helps

      Installed the new coil packs and plugs and the throttle response feels a little crisper and smoother in the 5K plus RPM range. Haven't been out on a road trip yet to check for any change in MPG. But I didn't buy the car to really care about the MPG. Would you? 2017 GT Premium, 6 speed manual, GT performance package, great toy!

      Would buy again

      I installed these at the same time as the SR Performance throttle body spacer so exact results may be influenced slightly. Definitely a smoother idle, I haven't noticed any MPG gains as of yet but the engine does feel as though its over all running better. Installation was a breeze, under an hour spacer included..

      SR Performance

      This coil pack kit is the best bang for your buck. It took me about 25min with basic hand tools to install. The hardest part was disconnecting the stock coils making sure I didn’t want to break anything. Throttle response Increased more than expected. Best part I feel more power at lower RPM’s.
