More Horsepower! The stock BOSS Mustang came with an awesome 444 Horsepower and 380 lb/ft of Torque from the factory, but after installation a ProCharger-equipped BOSS Mustang can make 660 or more horsepower at the flywheel. Thanks to the industry’s coolest charge air temperatures, the unmatched power gains are delivered with maximum reliability and everyday drivability.

High Capacity Intercooler. If you have the desire to continue modding your Mustang even after adding a ProCharger Supercharger, then this is the Kit for you. The race air-to-air intercooler included with the Stage II Kit has a higher capacity than the High Output (HO) Kit. This Stage II kit will accommodate additional modifications as you continue to transform your Mustang into the highest horsepower beast possible.

Complete Kit. The ProCharger Stage II Intercooled System comes 100% complete, and includes ProCharger P-1SC-1 self-contained supercharger, air-to-air intercooler, intercooler tubing, brackets, 52lb/hr fuel injectors, ProFlow bypass valve, and computer programmer.

Application. This ProCharger Stage II Intercooled Supercharger System is specifically designed for use on the 2012 to 2013 BOSS 302 Mustang equipped with the 4 valve 5.0L coyote engine.

Technical Notes. Minor trimming to the interior of the stock front bumper cover is required to accommodate the larger front mounted air-to-air intercooler. This Complete Supercharger Kit is designed to be used on stock applications, as Procharger will only provide a tune for the stock motor with stock exhaust or most aftermarket axle-back and cat-back exhaust systems. If your vehicle is no longer stock and has been upgraded with an aftermarket throttle body, cold air intake, headers, off-road mid-pipe, etc..., Procharger will not be able to provide a tune for your modifications. For modified vehicles, it would be best to purchase a Tuner Supercharger Kit so you can have a local Dyno Shop custom tune your vehicle with your aftermarket upgrades.

Please Note. Procharger Supercharger Systems are built to order for our customers and accordingly, we require you to submit additional information about your vehicle using this form. Because of this there is a 14 day lead time on orders once your information is received.

Once the Customer Information Form is filled out, please email it to with your Order Number in the Subject line, so the order can be processed.

Will this fit on a 2013 and 2014 Shelby gt500? If not, why is it under the gt500 section?

  • Hello! The Procharger Stage II Intercooled Supercharger System is only designed to work on the 10-13 Boss 302. I'm not sure why it is listed under the GT500 section, but we will work to correct that.


How much weight does it add to the car?

  • Hi, This supercharger will add around 130lbs of weight.

I want to do the boss 302 intake manifold on my 2013 GT. So when I buy the pro-charger, should I get the one for the boss, or the one or the GT?

  • If you have a Boss 302 Intake Manifold installed, you will need the Procharger Stage II Intercooled Supercharger System for the Boss. The only difference between the two Kits is the tubing for the manifold.


GT with Boss 302 Intake Will this system work for a 2012 gt with a Boss 302 Manifold installed? If so are there any other parts I will need to order to make it work? I realize the JLT cold air intake I have now won't work.

  • The Procharger Stage II Intercooled Supercharger System (12-13 BOSS 302) will not work with a standard GT as the Boss 302 motors are slightly different. We do have the same Procharger kit that will work with the Boss manifold for a GT. The link will be attached below.

    Transform great car into Beast Mode

    This Procharger kit fit well and the performance is great, and the look of this polished kit is really nice. However one big issue is the noise of the new high speed cooling fan, it is like a small turbine. ATI must do something to address this issue as it is a problem (maybe a re-design of the blade would fix this issue) it is bad enough that i can't recommend the kit to other BOSS owners until it is addressed.
