      Review & Installation Video

      I’m Justin from, and this is our detailed breakdown of the JLT Series 3 cold air intake system for the 2005-2009 Mustang GT. The first thing I notice when taking a look at this intake is the sheer size of everything, from the tube itself all the way down to that air filter, that’s going to be the big distinguishing factor with this intake versus some of its competitors. The series 3 features a massive 110mm MAF housing, which is one of the largest on the market today. This total combination is going to equate to more horsepower and torque at the rear wheels, and increase throttle response. The JLT features a 4.5” molded ABS plastic tube which is great at resisting engine bay heat especially when paired with that included heat shield. A nice thing about the series 3 is that it incorporates the MAF sensor housing right into the intake tube itself, eliminating the need for excess couplers or housings which can actually hurt your air flow. Due to the very large size of this JLT intake, running a performance tune is an absolute must, but before we go installing the intake and uploading our tune, we want to get a baseline number from our 06 GT back there just to see where we stand. With our baseline run out of the way we’re going to get to installing our intake which should only take us about an hour using standard hand tools. As I mentioned earlier, in order to properly run this JLT intake you will need a performance tune, we’re going to use our custom Bama tune which should really make the most out of our kit. This is going to do a couple of things for us, this is going to optimize our spark timing, adjust your variable cam timing, and get those air/fuel ratios right in the sweet spot. You’re also going to see improved throttle response as well. With our intake installed and our tune uploaded, let’s turn the rollers one more time and see how well the Series 3 performed on our GT. So our baseline run with our 2006 GT gave us 277 horsepower and 282 ft/lbs of torque. With our JLT installed, we put down 300 horsepower and 316 ft/lbs of torque making for a peak gain of 23 horsepower over our baseline numbers, and gains of 30 horsepower and 32 ft/lbs of torque throughout the curve. The Series 3 from JLT is for the Mustang enthusiast with all out performance in mind, the price is very competitive with other cold air intake kits on the market today, especially when you factor in how well it performs. Of course the added need for a tune will factor in to the overall price in the long run, but if you’re looking to get the most out of your naturally aspirated or supercharged 3 valve 4.6 motor, then the Series 3 is definitely worth checking out.

        JLT leads the way !

        Im not a fan of the mount system for the heat shield, and found it nessesary to modify it for installation, but the overall priduct, and effectiveness of the part is phenomenal. I would absolutely buy this again.

        Get it

        Product arrived in 3 days which was good. I have a 08 Bullitt which comes with the ford racing cai. I have o/r h pipe and borla atak catback with a tune. Nothing major.. Changed the ford racing cai for the jlt series 3 and got it retune and the car ROARS now after 3500rpm. I should've been did this.. The gains are very noticeable..

        CAI Great fit and noticable seat of the pants feel

        Went on easily. Only issue was the PCV line was too short. Had to purchase some new hose to replace it. Noticable feei on the seat of the pants dyno. Also love the change in sound from this addition

        Easy Install and Noticeable Gains

        First off, the shipping was quick. Once I got it, install was a breeze. Tuned the car to it. Very noticeable throttle response and power gains. My car had another brand on CAI on it prior to changing to this and the difference is night and day. It looks great under the hood and does what is said it will do. By far the best intake system I've had on any of my cars thus far.

        I installed this in less than an hour and it was a breeze. Not too much performance gain has been noticed but once I step on it and get up over 3k rpm my Borla Stinger Cat-backs really roar! What a sound! No MPG gains have been noticed either, entirely because my driving style will not allow it! Paired with a Bama race tune this is a must add.

        Jot and tune

        Very disappointed with with this. First of all AM should give a disclaimer that there is a good chance you will get a check engine light after install, also been back and forth for two weeks with tuning department trying to figure out what’s wrong. I’m not a tech guy so this has been frustrating!

      can i drive twenty miles to my local exhaust shop without installing a tune I want to install thus CAI at home then drive to my local exhaust shop to have my x-pipe put on then tune the car with the bama tune will it be safe to drive the car less than twenty miles without the required tune

      • its completely safe you can drive a infinite miles. check engine will came on because there's more air flow incoming thought the mass air flow sensor so check engine will turn on after your tune check engine will turn off because maf sensor will be recalibrated

      I just installed this intake on my 2007 gt. It is stock except for 4.10’s and I have the sct x4 tuner. I installed this intake and selected the jlt intake on my tuner, on my test drive I felt a big decrease in power and my check engine light came on. Says it’s running lean on bank 2?! Any suggestions? I’m also installing the hot rod cams this weekend.

      • This JLT Performance Series 3 Cold Air Intake requires a custom tune and will not work properly with an off the shelf tune file (OTS). We would highly recommend speaking to a tuning shop or Bama Performance regarding your application and the necessary tune file.

      I purchased this CAI a while back. While having some work done at a local shop they misplaced the two screws for the MAF. Is there any way I can just get two more of these screws?

      I have an 08 Bullitt, what hp gains can I expect if I replace the factory CAI with this JLT series 3? I have a hand held tuner.

      • When combined with a tune, the JLT Performance Series 3 Cold Air Intake will provide performance gains of up to 25-30 HP and 20-25 TQ
