    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.

    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.

      Great engine visual upgrade, easy install

      Great quality product, easy install, good fit and makes the intake look a lot sharper than the previous stock filter/heat shield. Performance gain does seem minimal, though, even after a Bama 93 Race tune. But hey, 10-15 hp gain isn't exactly a massive leap and is normal for these bolt-ons.

      nice intake

      great intake for anyone with a Mach 1 that wants to keep the shaker hood functional. The only part that was hard to get to fit was where the snorkel connects to the new heat shield. Other than that good intake.

      love this kit

      First this kit really helps to clean up the engine bay and looks great too. the shield does not completely block out the engine compartment air from entering into the filter as does the factory unit, but it blocks most of it. also i highly recommend that you put the filter, tube, maf assembly together first; then connect the shield to the shaker tube and see where the shield covers the filter and see if the mounting hole lines up. mine did not line up and was 1" off. easy fix i drilled a new hole in the plastic shield to mount the cover properly. I had first tried to mount the shield in the original hole it came with but it caused the entire inlet tube assembly to be moved back that extra 1" causing fitment issues with other pieces and would not allow for proper clearances. it also was causing the shaker tube to be bent more than it wanted to and was putting undue stress on it. just let the shaker tube shield combo rest in its normal location and mark where you need to make a hole for mounting. this will make the kit fit way better than trying to force it into the original mounting hole. NOTE** my car had been in a front end collision and even though it had been professional fixed, may be the reason why the mounting hole did not line up.** All in all, a great kit i highly recommend to all Mach 1 owners. only gave 3 stars on performance because in order to feel any real gain the car would need to be tuned for it.

      Quality Product

      Installed this at the same time i installed a spectre intake on my girlfriends cherokee....her intake was about 1/2 the cost of mine lol it was noticeably lesser in quality too. this intake the clamps are stronger ones, everything fit snug, no modifications needed. took about 10 minutes to put on. her intake on the other hand which was 1/2 the cost required modifying the heat shield and the clamps were not nearly as nice or strong. This is definitely a good solid product for the price, you're getting what you pay for.

      Perfect Mod

      Bought a KandN air filter for my Mach 1 it kept bogging the car down. So I decided to buy the JLT and it was so much better. So much more power. Definitely worth every buck.

      easy install

      The JLT is the easiest cold air intake i have ever installed. The instructions were very poor though, could not see the words like the ink or toner was out. I did not see a mpg gain it actually went down a bit, better response and power range was gained.

      BREATHE DEEPER

      It was a straight forward install, 20 minutes. The heat shield fit was not exact. Runs smoother through the rpms, the mpg is around the same if not lower. Have gotten as high as 23mpg with stock intake with paper filter, average is around 21-22mpg. Right now 20 mpg, have been driving harder though. Highly suggest cleaning mass air flow sensor.

      Easy Install

      super easy to install, piece that covers filter and hooks up to factory tube to shaker was the only thing that gave me trouble. My advice is connect it first then screw it to the filter piece.

      JLT RAM AIR FOR MY MACH1

      Hello I am going to tell you my experience with the JLT RAM AIR INTAKE. Quick back story I bought the MACH1 with a slightly modified stock air intake. Had a KandN drop in air filter and that secondary square box that helps with air pressure (some German name for it) and it is connected to the tubing was gone and capped. When I de-snorkeled the stock housing for the air filter, I knew I got a performance gain. The engine had to reset it's self (what I mean by that is you heard a loud click of it adjusting time and spark). Present: The JLT was simple but tough to install, everything was tight and make sure read the instructions or watch a video so as not to reverse the metal bands. I am very please with it, easy to put on and looks great., now the meat and potatoes. CONS: Instructions was not that clear on the paper as far as reading and description. The air filter house is a tight fit, in fact to tight it suffocates my air intake. I had to take it off, due to my acceleration WOT was nonexistent. PROS: I don't know about HP or TQ increase however, the throttle response has vastly improved (once I took the air filter housing off), especially when I heel and toe in corners. Plus the sound of it sucking in air is pretty cool, when I can my acceleration medium and I can hear it over the engine and exhaust. I RECOMMEND this mod it cheap and easy and performance gains is good. Plus has reusable air filter, which means your not destroying forests to have fun a little LOL.

      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.

      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!

      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.
