K&N 57 Series FIPK Air Intake Kits represent a dramatic performance improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded intake tubes that can reduce air temperature and decrease sound over a metal tube. Air flow restriction can exist between the air filter and engine reducing the benefits of a K&N performance air filter. K&N air intake kits virtually eliminate restriction in the air path by replacing the filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which in turn adds power.
It has only been on a week but it seems the jeep has more spunk or at least it sounds that way. It took me about 2 1/2 hours to install but this is the first one I have installed and it would be much less time if I were to do it again. I'm looking forward to more HP and miles per gallon.
Awsome make jeep sound better
Nice clean installation, easy to follow instructions. great fit and quality
Surprisngly sounds better with only a intake, better gas milage and much faster response when i stomp my go pedel. I cant wait to add a exhuast system and see how they complment eachother. totally worth it. My 93 Grand cherokee 6cylnder loves this add
It was easy to install.So easy you dont even need instructions. Noticed hp gain. It has a nice roar to it when you have to give it some gas
