Description
Increases Spark Energy for More Power. Are you running a supercharger, turbocharger or a nitrous setup on your Coyote powered GT Mustang? If so, then you should seriously consider upgrading to a set of Granatelli Motor Sports (GMS) Pro Series Extreme Coils. The stock OE coils are weak by comparison and are prone to spark blowout under forced induction. Where the GMS Extreme Coils produce an amazing 65,000 volts, that's 45,000 more volts than the factory coils, which results in more power, better throttle response and no chance of spark blowout. This GMS Coil Kit will add up to 12HP on naturally aspirated Mustangs and an impressive 25HP on turbo or supercharger setups.
Better Fuel Economy. GMS Pro Series Extreme 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 Extreme 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 Pro Series Extreme 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 Pro Series Extreme 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.
