Product Information

Average Price: $267.60
Manufacturer: K&N
Yes: 10 / No: 0

Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Kit is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series intakes have a polished aluminum finish. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions)

Pros: Better throttle response and mean sound when the pedal is to the metal!
Cons: Under normal acceleration makes high pitched whistle sound but you get use to it.
Recommended? Yes

Comments: I found this intake for a steal price on craigslist and it was in great condition. The install was easy except for getting the intakes body into position to line up with everything was tricky. The install took about an hour and a half (this includes searching for tools in the garage and drinking beer). After the install the Jeep has a more deeper sound when you give it gas. However don't be alarmed that it is not gonna be a huge difference when you start it up and just casually drive down the road. The throttle response is much better. When you put the pedal to the metal this is when you will notice the difference! She roars!! The only negative thing about it is the annoying high pitched whistle under normal driving but you get use to it to the point that you don't even notice.

Price: $286.99
Pros: Makes it louder and helps on the MPG's
Cons: Doesn't connect to the throttle body, it uses stock airbox.
Recommended? Yes

Comments: I like the K&N 77 Series. It helped me from 12 mpg in city to mid 15's. It gives the V6 a nice sound, and looks sharp! Only downside is it uses the stock airbox unlike the 57 Series FIPK intake for the WK. For the money it is worht it if you are going for looks. Im going to uninstall and get a Injen intake instead. Its all about what you really want out of it

Comments: Intake was very easy to install, increase in performance. A little increase in mpg is you can stay off the gas! Sounds great when your right foot is a little heavy. Notice a difference while passing at high way speeds.

Price: $299.00
Pros: Sounds great, more horsepower, better MPG, easy to install
Cons: none
Recommended? Yes

Comments: me and my buddy installed this kit in just over an hour right in my driveway, it was very simple, the only part we struggled on was removing a few screws holding the stock filter box because they were under the fender and sometimes had the plastic fenders covering them, i would recommend having 2 sets of the sockets, its a great product and in the end i would more than happily refer this product to other WJ owners
