    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

    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.

    If through time one of the coil goes bad, how would i be able to replace a coil individually? Do y'all offer single coil replacement?

    I'm trying to decide between the SR Performance 4V Coil Pack Kit and Ford Performance Ignition Coil Set. Could you tell me what the difference between these 2 are, and what you would recommend going with?

    bambam

    • The SR Performance 4V Coil Packs and Ford Performance Ignition Coil Set are similar in design, however the SR performance coils will output significantly more voltage (42k vs 20k) allowing for a hotter spark.

    Would a 125 shot nitrous 2013 5.0 benefit with these?

    BryanH

    • These SR performance coil on plugs would work with a 125 nitrous shot as long as you will also be using a colder heat range spark plug as well.

      Coil Pack

      Good product, smoother idle, slight increase in throttle response. These will not connect to 16 GT’s built after Feb, Ford changed the coil pack connector to a smaller housing.

      Perfect replacement

      Was having an odd miss every so often, ordered these and spark plugs. Installed both and it runs way better. Granted the spark plugs I removed were way off on all the gaps from .45 to .60. Nonetheless they look awesome, it runs better and a very simple install.

      Sr 42 volt coils

      Worth every penny decrease time of acceleration took out hesitation of idle buy however on another note I am impressed with the product but 42 volt is great but what about 60 volt coils doesn't matter you can't go wrong with them.

      I was sure that it will make a difference, but did not expect that much of the power gain. YEEEH The performance gain is the best for the money that you spend. fist tank gained 16KM and I was driving the car mostly in sport mode. NICE.

      Satisfied Customer

      Coils came individually wrapped and packaged safely. Install was a breeze (Approxiamtely 45 minutes taking my time to not break connector clips). Coils themselves are well made and appear to be of high quality. Car started immediately and I let idle for 2-3 minutes. On test drive acceleration was noticeably improved and power delivery was improved over 4000 RPM. Will monitor MPG, still too early to tell. Overall very happy with purchase. Thanks AM! -JBG
