Product Information

Average Price: $217.04
Manufacturer: K & N
Yes: 75 / No: 5

The Generation II FIPK® is K&N's ultimate performance product, designed to increase power by as much as 10%. Most FIPK's are street legal in all 50 US states and come with a Million Mile Limited Warranty. 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

Pros: Intake tube design.
Cons: K&N filter
Recommended? Yes

Comments: This kit came installed on the jeep when I bought it so I can't give an accurate comparison from the stock intake design, because I never had it. The first thing I did was clean the filter and noticed how easy it was to see light through it and how thin the filter media was. I then realized how the inside of the intake tube and throttle body were coated with fine talcum power-like dirt. Just a thin layer but enough to cause my throttle body to turn black. I eventually decided to trash the K&N filter and just installed a paper element cone shaped filter from Orielly's. It was easy to make the paper filter fit securely. I'm not a fan of K&N filters since they let the fine dirt through. But the intake design is solid. I like the straight-shot style tube and the super smooth finish of the inside of the tube. It's also very easy to remove and re-install the intake with nothing but a small flathead screwdriver which comes in handy when doing engine work. The quality of the kit is fantastic and I have no doubt it will last the life of the vehicle. I'm sure the stock airbox works just fine, but I have no doubt the K&N system is feeding my engine all the air it wants with no interruptions.

Comments: Love this kit. It allows the jeep to breath better and it sounds almost as if the engine is turbo charged. It has that same high pitch hiss.

Price: $250.00
Pros: -Million mile warranty -Washable -May or may not improve air flow -Filters way better than paper filters, and a stock airbox.
Cons: -Requires a recharge kit for cleaning. -Location sucks to begin with, but the provided heat shield could be better. -Filter doesn't do as good a job as the K&N filters that replace stock airbox paper filters
Recommended? No

Comments: I can't remember how much I paid for my FIPK.
It was a few years back, and it was when I first started working on my XJ.
Since it was the easiest of the mods I had lined up for the summer, I slapped the FIPK kit on, and took er' for a spin.
The first thing you'll notice is a deeper exhaust note at lower RPM's.
Throttle response may or may not seem snappier.
As for gas mileage improvements, I didn't really pay attention.
Either way, you don't have to keep buying stupid paper filters anymore, so that's a big plus.

Price: $165.00
Pros: added fair amount of HP, Now my top speed is around 90 mph instead of 70. Slight improvement in gas mileage.
Cons: gap around tube at heat shield, butts up against intake manifold with flexible coupler and a couple of clamps, not a perfect fit. Chintzy for the price.
Recommended? Yes

Comments: I think it would be very easy to make your own with a cone filter and the stock tubing. or even PVC.
