    Video Review & Installation

    Hey It’s Mike from Today we’re going to take a look at the JLT cold air intakes for your 2011 Mustang GT, one made out of durable plastic, the other out of lightweight carbon fiber. These cold air intakes replace your factory restrictive airbox. By increasing the airflow to your Mustang’s engine, you’ll notice increased horsepower, better acceleration, improved throttle response, and better fuel economy, especially when you add a Bama tune. These really are must have modifications for performance. Before installing the intakes, we did a stock Dyno run to get some baseline numbers. Stock, our 2011 Mustang GT automatic put down 344 horsepower and 302 ft/lbs of torque. The JLT carbon fiber kit comes with a high flow reusable air filter, lightweight carbon fiber inlet tube, silicone hoses, all the hardware, and a plastic heat shield. First we installed the JLT carbon fiber kit. Along with the cold air intake, we also installed one of our 93 octane Bama race tunes. A custom tune from Bama performance adjusts engine parameters to maximize your performance through optimized air/fuel ratio, spark advance, enhanced throttle response, variable cam timing, and for automatics, increased shift firmness, and adjustable shift points. After installing the JLT carbon fiber intake and a Bama race tune, we did another Dyno run. With the JLT carbon fiber intake and our Bama tune, our 2011 GT put down 365 horsepower, and 341 ft/lbs of torque, gaining as much as 57 horsepower and 55 ft/lbs of torque throughout the curve. Next, we installed the JLT cold air intake with the plastic tubing. The JLT kit comes with a high flow reusable air filter, plastic molded inlet tube, silicone hoses, all the hardware, and a plastic heat shield. After installing this kit with our Bama race tune, we did one more Dyno run. The JLT with the plastic tubing made an identical 365 horsepower and 341 ft/lbs of torque, while also gaining us 57 horsepower and 55 ft/lbs of torque, throughout the curve. Both JLT intake kits were easy to install with simple hand tools in under an hour’s time. Whether you decide to go with the lightweight carbon fiber intake tube or the plastic intake tube, they’ll both gain you as much as 57 horsepower and 55 ft/lbs of torque.

    Custom Bama Tunes specific to your vehicle. When you order a tuner, you aren't just getting a tuner - you are getting the tuner and 2 dyno-tested custom Bama tunes:

    • Performance V2 (87-93 Octane) - The Performance Tune offers a seamless blend of power, performance and drive-ability. Improving the overall driving experience of your Mustang, the Bama Performance Tune improves vehicle acceleration, increases power throughout the entire RPM and improves throttle response with revised timing, fuel, and TiVCT maps. Automatic equipped vehicles offer an aggressive shifting map to provide more aggressive transmission settings. This tune is suggested for the aggressive daily driver that is looking for more "get up and go".

    • Race V2 (91-93 Octane, E85, Race Fuel) - The Race Tune is designed for maximum performance and ensures the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory as timing, TiVCT, fuel, and throttle response settings are very aggressive. Automatic transmission settings implement entirely new shift points, torque converter changes and firmness settings designed for Track use.

    Nitrous (91, 93, E85, Race Fuel) - Our nitrous option can be added to any of our previously mentioned tune options, but only for 91, 93, E85, or Race Fuel.

    Technical Note About Fuel. Use of E85 will require larger fuel injectors such as Injector Dynamics ID1300 or Ford Racing 47lb/hr Injectors. Unleaded race fuel can also be used, but Stoichiometric points must be supplied.

    Easy to load; easy to restore. Not only are the custom tunes easy to load on your vehicle, it is just as easy to restore your factory settings. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

    Install Note: When installing the filter on the air tube, please be sure not to slide the air filter down too far on the tube as it may cause surging issues.
