Ford Performance Now Offers Shelby GT350 Parts for the Mustang GT

Do you happen to own a 2015 to 2017 Ford Mustang GT, but the 5.0-liter Coyote V8 lacks the fizzy nature of the rev-happy 5.2-liter Voodoo V8 in the Shelby GT350? Have I got good news for you!

The boys and girls at Ford Performance have listened to S550 owners and complied with their wish to squeeze more ponies from the Five-Point-Oh. At the present moment, three emissions-legal performance calibrations (a.k.a. power packs) are available for the sixth generation of the Ford Mustang GT.

The first of the lot is dubbed M-9603-M8 - Power Pack 1 and it’s relatively cheap. For $539, you get a high flow K&N air filter which is good for a bump of 13 horsepower and 16 lb-ft (27 Nm) over the stock output. At 1,500 rpm, Ford Performance promises a gain of 40 lb-ft (54 Nm). Not bad at all.

If that's still not enough, the M-9603-M8A - Power Pack 2 is only happy to step in. Priced at $949, the second of three power packs prides itself on a Shelby GT350-specification cold air intake with an 87-mm throttle body and an intake adapter. Ford Performance tells that these parts add 21 horsepower and 24 lb-ft (32 Nm) to the mix. At 1,500 rpm, that'll be 40 lb-ft (54 Nm).

And finally, please put your hands together for the M-9452-M8 - Power Pack 3. It’s not cheap at all ($2,395), but what you get in return makes it worth it. Compared to the intermediate pack, the third performance packages adds the intake manifold from the Ford Mustang Shelby GT350 (pictured). Hence, the Mustang GT gets a bump of 37 horsepower and 5 lb-ft (6.7 Nm). At 7,500 rpm, Power Pack 3 adds 60 horsepower to the 5.0-liter Coyote V8.

Best of all, though? All power packs are covered under warranty. The following list represents the features included in the three kits:

  • Fits 2015-2017 Mustang GT
  • Features exclusive no-lift shift strategy and enhanced throttle response
  • Ford Performance calibrations feature exclusive Ford proprietary software and engineering
  • Ford Performance calibrations are 50 state legal with CARB EO
