More Usable Horsepower. With a JLT Performance "Next Generation" Ram Air Intake installed under the hood of your Mach 1 you can expect to see average performance gains of 10 to 14 horsepower at the rear wheels. In addition to an increase in horsepower you will also see an impressive improvement in throttle response.

Keeps Shaker System Functional. Unlike other Mach 1 intake kits on the market, this JLT Ram Air Intake not only improves the performance of your Mach 1, but it also allows you to keep your factory shaker system setup fully functional.

Heat Shield Included. The JLT Performance Ram Air Intake includes a vacuum formed ABS plastic heat shield that not only looks great, but blocks out excessive under hood engine heat at low speed and idle that can rob you of power.

Money Saving Reusable Filter. JLT ram air intake kits come complete with a 4x9 high flow reusable S&B brand air filter. So that means there is no need to go out and buy a new filter every few thousand miles. Now you can just clean the filter, re-oil it, save money, and go!

Easy Installation. The JLT Performance "Next Generation" Ram Air Intake kit was designed to install with just basic hand tools. No extra modifications or special tools are required for an easy 1 hour installation.

CARB Certified. Best of all this Mustang JLT Performance Cold Air Intake Kit is 50-state smog legal under Carb EO# D-671.

Application. This JLT Performance "Next Generation" Ram Air Intake System is specifically designed for use on the 2003-2004 Mach 1 Mustangs equipped with the DOHC 4.6L V8 engine and does not require re-tuning the vehicles computer for operation.

Technical Note. Will not fit with most strut tower braces.

will this work with the CDC shaker system I have the CDC Shaker package on my car and i know it's a little different than the Mach 1 setup

ozzyisgod666

  • If it is the regular GT with the 2 valve engine, then no it will not fit. The mach 1 has a different throttle body than the GT. Get an intake for that specific throttle body. Hope this helps!

First generation I have the first generation model of this intake, I like it but was wondering if anybody knows if there are an pros and cons to maybe upgrading to this generation?? PLEASE HELP

SIKMACH

  • You might get a couple extra horses if you upgrade to the JLT Performance Next Generation Ram Air Intake (03-04 Mach 1) and that's up to you if you think buying a whole new CAI for maybe a little more power. Otherwise, if it ain't broke, don't fix it!

    Mach 1 JLT RAI

    Works well with tune! Give it a 3 for fitment because the design of the heat shield does not fit well causing it to push on the shaker making it crooked and a bit raised on the passenger side of the shaker - other than that works well!

    I bought this kit knowing some people have had problems installing it. Everything that came with the kit seemed of good quality. Installation was a breeze! Don't tighten any clamps until you have everything in place. I have absolutely zero clearance issues. Everything fit perfectly. I'm really not sure how people have problems with this kit. It took me about 30 min to install. The car sounds great now. You can deff feel more power up top. Low end torque has been sacrificed a bit but hardly noticeable...we have enough anyways haha

    This product was the best bang for the buck and its worth every penny.

    At American Muscle I talked with dedicated car enthusiest who took the time and explained to me what will work and what wouldn't work for my car and that's what seperates them as a company from the rest because they care. You spend your money right the first time.

    Good Gains

    Added this CAI to an Accufab 60mm throttle body and noticed immediate gains. Heat shield material seems a little cheap and flimsy, and filter was a tight fit, other than that installation was a breeze, I spent more time piecing it together than installing. I feel with a tune, it will perform better.

    JLT RAI - Sounds good and looks good

    I'm pretty happy with the purchase of the JLT RAI. It was easy to install, took about 1/2 hour....fit right in, no problems. Took it out for a test ride and you can hear the motor sucking the air in. Didn't really feel any drastic power gain, but it sounds good and looks good, so I'm happy. I am also posting before and after pics. Thanks JLT and American Muscle.

    Fits like a glove

    I was skeptical about getting this intake after I heard about others having trouble getting it to fit but I had no problems. Simple, easy install and connected right up to the shaker. You can really hear the air sucking now. Great product for anyone looking to upgrade from the stock Mach 1 intake.

    Exactly what I expected

    Easy install and the gas pedal is a bit lighter. You can definitely hear the engine inhale now. A little better throttle response as well. This aftermarket piece looks 10 times better than the factory air intake.

    JLT Performance Next Gen Ram Air Intake for Mach 1

    Installs easily in about 30 to 45 minutes. I took extra time to clean the area underneath the mass airflow sensor that once reinstalled would not be accessible. I also painted the plastic intake tube competition orange. I have not purchased a tuner yet so I can't comment on any performance gains.
