    I am using a stock 2018 throttle body on mustang GT will i need a new Silicone Reducer Coupler if i use the GT350 throttle body In the future.

    Will the JLT CAI or tune void the warranty on my Mustang?

    • Generally cold air intakes that require tunes will void the warranty on the vehicle. We recommend contacting your dealership to confirm what will and will not void the factory warranty.

    Will this product work with the Active Exhaust option? I recently tried a K and N CAI, and due to the opening and closing aspect (air flow I assume) of the AE, the engine light will stay on and K and N themselves told me their CAI was not compatible. Are there any CAI's yet that will work with the Active Exhaust and if so, which ones and is a tune required?

    • The JLT Performance Cold Air Intake is compatible with the Active Exhaust.

      Tight fit, but it works

      Pretty easy install. The hardest part is the sound tube removal. Yes, it is a tight fit and I had to drop the hood to get it to shut the first time. It’s shuts fine now and runs good paired with a BAMA Performance tune and cat-back exhaust. Massive inlet tube and filter. I’ve only used KandN and Steeda intakes prior to this. JLT did a good job maximizing the place and the quality is good as well.

      Simple. At first!

      I bought this CAI even though the reviews warned everyone it was a tight fit. Working as a Mechanic most of my life I paid little attention to the complaints since I figured most of it was due to lack of experience and a small side of whining. I now apologize to those writers. After about 15 minutes I had the old out and the new one in, I have not attempted to close the hood at this point. Tried to close the hood and instantly I recalled all the reviews. About a hour later, a cutoff tool, and a lot of dust later it was shutting perfectly. I tried all of the advice from previous reads. Only get so much room adjusting at the throttle body it all came down to the box and the air filter being to large. Had to make it sit lower. It does work well with the Lund tune I installed. But a lot of work for something that there shouldn’t be.

      Awesome setup from JLT

      Got the kit installed in under a hour. Reading the other reviews about fitment there are some things to look at for install. The intake is BIG! All of the adjustment is in the silicone coupler at the throttle body. Leave the clamp loose that goes from the coupler to the tube and pivot the tube to get it lower in the car. Tighten the clamp once you have it where you need it. My tube doesn't touch my hood after adjustment. I'm happy with the install and performance! Thank you American Muscle and JLT Performance!

      Good Gains Poor Fitment

      Installed this intake on my 2018 GT along with a SR Performance throttle body spacer...long story short it wont fit with a throttle body spacer. Spoke to JLT about it and they are now aware of the clearance issues. Removed throttle body spacer, and the hood still wouldn't close....the angle of the intake tube @ the throttle body is incorrect and the coupling needed to be trimmed. I trimmed it from just above mid circumference down to the base (underside of the TB) at a slight angle and after a few attempts at trimming the coupling (about 2 lines on the coupling) I re-installed it and now the hood closes perfectly with no issues. JLT needs to make their couplings already angled at the base or come up with a different design all together but all in all the gains were worth it with the VMP 93 octane tune!!

      Size issue

      Do not get this system unless you do not mind cutting a hole in your hood. After completing the install and flashing the tune I attempted to attach the engine cover and realized it didn't set down flush onto the engine due to it hitting the plastic air tube. Without putting the cover on I tried closing the hood without success. The oversized air tube did not clear the engine compartment preventing the hood from closing. Makes me wonder if anyone at JLT tested this product before it hit the market

      Fitment issues but true performance gains

      I made this my 2nd mod on my new '18 GT. I put a JLT oil separator in as first priority, then a few days later I grabbed this cold air intake and a tuner from Torrie at Unleashed Tuning (E85 tune). I knew to run this air intake I'd need a tune, and I've dealt with Unleashed and Torrie in the past so I was excited when the parts arrived for me to do this next mod. I went to a friends shop to make sure if I had any issues that I'd have an extra set of eyes, I borrowed a ratcheting 10mm wrench from him and proceeded to do the install out in the parking lot. After about 20 minutes the swap was complete (really glad I borrow the ratcheting 10mm wrench for that nut that holds down the rear of the sound symposer. The install was straight forward, instructions aren't that great, but I had watched the install video so I wasn't worried about that. I went to lower my hood and leave and found that my hood didn't want to shut. I had to readjust the clamp and push the overly large intake tube to the maf down and reclamp in a different position. Hood still didn't wanna shut. So I checked for what was up and realized that the oversize air inlet tube is really waaaaay too big for the kit and the underhood fire mat was touching the air inlet tube even on pre-latch. I took a big gulp of air, lifted the hood about 18" and let gravity do its thing, and the hood shut and latched properly. Now you may think this isn't a big issue, but I do, especially since AM's install video doesn't mention this at all. If you look at the air inlet tube, its waaaay oversized and is necked down to actually fit the maf, if JLT woulda made this tube a little smaller it wouldn't have caused the fitment issue, and they coulda done that without sacrificing air flow at all. The kit is overkill for an otherwise stock engine, but it does look good under the hood (especially that huge filter). I wanted to write an honest review, you will have issues with shutting your hood, and if you don't wanna have to gravity drop your hood from 18" to slam it shut, then look for another cai for your '18. Overall I've been fair, I rate it as average on fit, but with a tune the performance gain rates a 5 star easily.
