    Video Review & Installation

    Hey I’m Justin with, and I’m going to be breaking down the JLT cold air intake, available in a textured black ABS plastic finish, or carbon fiber, fitting all 2011 and newer Mustang GTs. The Performance cold air from JLT is a tune only intake due to its absolutely massive 170mm diameter intake tube that does incorporate the MAF housing into the actual tube itself, making for a much cleaner look. Because this intake does not include a reducer insert like other aftermarket intakes, running a performance tune is an absolute must. Taking a closer look at the first option you’ll see that JLT went with a lightweight ABS plastic for the intake tube, which will be slightly better at reducing heat soak when compared to other metal intake tubes. JLT does offer the performance in a carbon fiber version which will offer all the same performance benefits as the ABS plastic version, but with a very cool carbon fiber finish that’s sure to look great under the hood, that is of course if you don’t mind spending a few extra bucks for the added bling. Included in the package you’ll find the rather large power stack reusable high flow filter, ABS plastic heat shield, all the hardware and couplers, and finally the intake tube itself. The nice thing with the JLT is it does include a bung to be used with the interior sound tube, if you’re not familiar with what this is it’s basically a hose which connects that bung to the firewall, and pumps all that intake noise into the cabin. If you’ve already deleted this, or you’re not a fan of this, you can always use the included cap to plug everything off. Alright, in order to see how well the JLT will perform on our Coyote motor, we need to see where the car stands now, so with that said let’s grab a quick baseline run using our automatic 2011 GT, and then get to work installing the intake. Removing the stock airbox and then getting the new JLT installed is something any backyard mechanic should be able to tackle in half an hour or less using basic hand tools. For automatic equipped cars, you will need to drill a half inch hole into the actual intake tube, and then use the included fitting to complete the job but really it’s not a big deal. As I mentioned earlier, due to the size of the mass air flow housing on the JLT, running a performance tune is an absolute must, otherwise you’re going to trigger a check engine light, so we’re going to upload our custom Bama tune, which is going to optimize our spark timing, adjust our variable cam timing, and should ultimately get those air/fuel ratios right where they need to be. Alright with our JLT installed and our tune uploaded, let’s make another pull on the Dynojet and see what kind of improvements this intake made on our 2011. Our baseline run using our automatic 2011 GT gave us 336 horsepower and 302 ft/lbs of torque, with our JLT/Bama combination, we put down 369 horsepower and 339 ft/lbs of torque, making for a peak gain of 33 horsepower over our baseline numbers, and gains of 37 horsepower and 60 ft/lbs of torque throughout the curve. The performance from the JLT is for the Mustang owner who’s looking for maximum power gains, and either has a tune installed already or plans on purchasing one along with the intake, and as always you can check out both options right here at
