Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume 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, reusable and easy to install with tools commonly available.

I thought hard about spending this kind of money for an air filter but when a gift card opportunity presented itself, I finally ordered this kit for my 2004 Jeep Wrangler Rubicon 4.0 liter. The kit came exactly as advertised and one must sign for it so prepare to be home on the delivery date or wait for the UPS guy to come back at his convenience. The kit came on the 2nd visit (my fault) and I immediately turned to installation. Some advice: Read the instructions first with specific attention to the parts diagram. This will help you later when doubts may arise about which washers, nuts, and bolts go with what. I jumped right into it and found that I had to digress back to the diagram at the top of the first page. Frankly, I was a bit embarrassed since the device is very easily (and quickly) installed with minimal fuss. Here is the "be careful" part I mentioned. Once you install this, you WILL get more power and snap out of the previously somewhat lame motor, even if you had the OEM replacement K&N filter installed in the stock intake. This kit also sounds much cooler when you stomp on the accelerator. Before, the 4.0 California smog motor made all sorts of ridiculous noise but the Jeep really didn't go much of anywhere in a hurry. It goes in a hurry now and if you are not careful, your foot will be much more frequently in the gas pedal. In fact, I made a bad call in traffic this morning and turned out into on-coming before I should have. With the added snap and pop, I was able to get the Jeep up to safe speed before I caused a crash. So all in all, sounds cool, looks cool, gets up and goes. If you've been kicking this around in your head, go ahead and do it. Like me, you will probably kick yourself for the 70,000 or so miles that you did not have this.

Extremely easy to install, if you have air conditioner on your jeep, you will have a smal dificulty installing the filter plate housing. There is a screw that you must install in the radiator with a small plate, well that screw you will need it larger because of a air conditioner's hose that limits the space there. Great product you can feel the difference inmediatly, great torque and acceleration. It also looks espectacular.

Great addition to your Jeep Wrangler 4.0 6cyl. This is a MUST have! You can not go wrong with this kit. Instant HORSEPOWER for the 4.0 6cyl. It took me more than 30 minutes to install it, thanks to many 12oz adult beverages that kept one arm occupied while trying to install this kit! The only thhing I would add is use MORE tape on your shipping box! When UPS deliverd this, the bottom of the box was just about to fall aprt and all pieces included.
