More Horsepower and Torque. When it comes time to replace your Mustang GT's old coil packs don't settle for OE replacements, upgrade for more power. By installing a set of Granatelli Motor Sports Street Fighter Coil Packs you will see an increase of 10+ Horsepower and 10+ ft/lbs of Torque at the rear wheels. These GMS Coils produce an amazing 42,000 volts, that's 22,000 more volts than the factory coils, which results in more power, better throttle response and a noticeably smoother idle. Street Fighter Series Coils are an ideal replacement upgrade for stock or lightly modded Coyote Mustangs searching for an additional boost in power.

Better Fuel Economy. GMS Street Fighter Coils not only improve the rear wheel power of your GT, but they also improve its fuel economy as well. After installation Coyote owners have reported up to a 10% increase in gas mileage. Because of the higher voltage of these Street Fighter Coils your spark plugs will produce a hotter spark. This hotter spark will burn the air/fuel mixture more completely releasing all of its potential energy which translates into better fuel economy and more power.

0 ohm Technology. Granatelli Motor Sports proudly manufactures their Street Fighter Coil Packs right here in the USA. Featuring patented “0” ohm technology GMS Coils use a silicone magnetic steel core that not only improves spark power, but has 0 ohms of resistance so all the spark energy of the coil transfers to the spark plug. This patented design also suppresses Radio Frequency Interference (RFI) and Electro Magnetic Interference (EMI) to effectively shield your Mustangs sensitive electronic components from interference.

Application. This set of eight Granatelli Motor Sports 4-Valve Street Fighter Coil Packs are designed as a direct fit performance upgrade for the 2011 to 2014 GT and Boss 302 Mustangs equipped with the Coyote 5.0L 4 valve V8 engine.

Smoother idle

I can feel the smoother idle, and a little better throttle response. Audio improved gas milage about 3 to 5 percent in my estimated opinion

Do these work on the s550 5.0s because I see others in the reviews with submodels that are 2016 so do they work or don't?

BillySAW951

  • We can not guarantee fitment on the S550 Mustangs. We recommend the GMS 4V Street Fighter Coil Pack only be used with 11-14 S197s.

Does GMS recommend a specific spark plug gap for these coils?

Charles

  • There is not a specific plug gap recommended to be used in conjunction with this GMS coil on plug kit, we would recommend the use of the factory plug gap specifications.

I have a 2016 mustang performance package Will it work on a stock mustang The coils. Also I'm going to need the spark plugs which one would you recommend me for use on those coils

JoelC

  • These GMS 4V Street Fighter Coil Pack are designed for 2011-2014 Mustang GT's and will not work with 2015-2017 models. In regards to spark plugs, we would recommend the NGK Laser Iridium Performance Spark Plugs, Item 64062 which are an ideal upgraded replacement. http://www.americanmuscle.com/ngk-iridium-3789.html

does this product require a re-tune. i already have a CAI,throttle body and ported stock manifold. also how reliable are they? ive read from other kits they die after about a year.

WHITECOYOTE

  • The GMS 4V Street Fighter Coil Pack (11-Early 16 GT, BOSS) will not require a tune however a tune would be more beneficial. The GMS is a great brand, one of the best for coil packs.

    Installed JLT CAI, BBK 85mm throttle body, Boss 302 intake on 2013 GT. Upgraded to better spark plugs and installed new coil packs. Installation was simple. Noticeable difference at high revs. Increased response, better acceleration. Less throttle when cruising. A noticeable difference and overall improvement when compared factory plugs and coils.

    Real easy to install, but be careful taking the clips off, i broke one and had to get the Motorcraft kit to replace it, the 2011 Mustang Gt idles better but i see no increase HP.

    good product

    After instalingl these coils I experienced better idle, a slight increase in throttle response and increased my gas mileage by almost 3.5 miles per gallon. However, with increase in throttle response it makes me drive it up to its potential. Increased gas mileage goes back down but it sure is fun to drive. Seems to be best coils out there for this application.

    Amazing!!!

    I can't believe this cool pack does the job!!!! It absolutely increases the HP and throttle response! I was skeptical at first till I realized the importance on a performance to unleash small details to a more powerful beast!!!! The drive and shifts are much smoother and throttle response is much sensitive. It's not hard to install but professional help may be important if your not familiar with the engine I would recommend. But I'm real please with this product for an additional mod for my GT! AM did it again.

    GMS Coil Pack

    So far so good. Be sure to check the heat range of you spark plugs and use anti seize. As you add power to your 5.0 build it will require a colder plug. The car seems to Idle better and has a quicker response. I have not had a chance to test drive it due to other work that I'm doing.

    easy to install and I think the petal feels a little quicker, but it could also just be in my head. Gas mileage... We drive our 5.0 fast so gas doesn't really matter lol

    great way to tune up your stang.

    My mustang had a slight misfire so i bought a set of GMS 4V street fighter coil packs and a set of factory plugs and i will say the car runs great. The misfire is gone and i noticed better throttle response a little more power and better milage. im very happy with the way the car runs now . note let your stang idle for a few mins and get some drive time after. by the next day you will see a difference. NOTE,DOUBLE CHECK THE SPARK PLUG GAP. i have a 2013 gt 5.0

    Excellent!

    A good compliment to your Mustang as these will burn off a little more previously wasted fuel and free up a few more ponies. Plus they are blue and who doesn't like blue?

    Good Value for your dollar.

    Coils came individually packed in bubble wrap and were a snap to install. I spent approximately 35 to 40 minutes on this install with little to no issues at all. After installation on my 2014 GT it appeared to have a smoother idle and quicker response time. The quality of the product was top notch and would recommend anyone wanting to achieve this type of performance from their Mustang at a reasonable cost compared to other name brands. Good bang for your dollar.
