"I recently installed the K&N FIPK Air Intake on my '04 Ram. Install time was a little over an hour and well worth it. It is absolutly amazing. The engine is quiet and stealthy as can be at cruise and idle, but the second you get on it...not even the radio can drown out the beautiful roar of the V8. Throttle response has been increased to what feels like its full potential. I would highly recomend this addition to anyone looking for a good bang for your buck." —Kevin B from Kingston, NY bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Jeep Liberty, 5.7L Hemi.
"Very easy to install, might have taken about 1 hour to install on my 2003 Jeep Liberty. The hardest part was getting the stock intake out but that was not that hard. When I started it for the first time you could hear how much easier it was breathing. Hope to see an increase in MPG but have not had it in long enough to tell!" —Mike D from York, PA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Jeep Liberty.

"I'm still not 100% sure if I a breather hose was supposed to supplied or if I was supposed to use the stock one, but even with the stock one, it all worked out and after about 45 min. of installation. Def feel a power diff. Only drag is that it threw the check engine light on." —Mr Matthew P from Chester, NY bought an AEM Brute Force Air Intakes for a 2003 Jeep Liberty.
