A definite improvement, better response time. The only thing to complain about is that it's a pain to take the filter out to clean it. There should be a quick clip connection to remove the filter not bolts that are hidden in the back and need a knuckle adapter to be removed.
Have had this installed in my 2014 Jeep JK for a year now. Have had no issue with this system. Vary easy to install. Felt like a different Jeep after installing the intake. NO real gain in fuel mileage average about 18.6 between Highway and City. Can tell a difference in throttle response. If you are looking for a intake that makes more noise when putting the pedal down then this is not for you. Its vary quiet to other intakes I have had on other cars in the past, But then again its a Jeep and not a JMD import. Also the intake stays vary clean even off-roading it, being in a closed box keeps a lot of mud and junk off the air filter vs my finds K&N 77 series. I would recommend this intake to anyone that's got a JK and looking for a good air intake.
Great Kit !!!
I installed the AEM Cold Air Intake today on my 2012 Jeep Wrangler Unlimited (Rubicon). The install was very simple, everything fit as if from the factory, and the instructions are the most complete I have ever seen. Initial 'Seat of the Pants' feedback revealed improved throttle response and it feels like there is a bit more power on tap. I'm looking forward to a longer performance run and mileage check.
I am also looking forward to enjoying the longer duration on air filer service that comes with AEM's dry filter technology. AEM has always been in the forefront of innovative performance enhancing products throughout the years and this kit is no exception. I recommend it for all fellow Jeep enthusiasts !!!
