I did this install for several reasons but the main one was to get rid of the stock air box so I could install an on-board air system. I also installed the filter because it is possible to dunk the air box while leaning your jeep on its right side. With the filter in the middle of the Jeep you have to go real deep to get it submerged.
Another bonus is advertised increase in power, fuel efficiency and never having to buy another air filter. However you do need to buy cleaning kits but they are pretty cheap.. I know many people argue that they give no increased in power or fuel efficiency but whatever..
Also people believe the air the K&N lets in isn’t as clean as the stock filters and others believe it’s more clean. Find out what I personally think at the bottom of this article as I’ll keep updates on my experiences with the filter.
Start by removing your stock air box and air tube.
Wow look at how much room you have already!
Take the stock air tube and cut off the flexible hose then clean to make sure no plastic bits get sucked into your engine. Place your air tube back on the throttle body.
Slide the K&N over the tub and tighten down the bolts. You may want to zip tie the tub down to where the accelerator cables are attached to make the system more secure.
You’re Done!
Conclusion
Right off the bat I noticed an increase in pickup off the line. I find the K&N whistled at certain speeds however it calmed down after a few days. I guess this whistle is a normal thing and nothing to be worried about its just the K&N doing its thing I’ve cleaned it 2 times already just to be on the safe side.
Updates
January 2002 – Its been 8 months since I put it on and it has seen 20,000KM and been cleaned 4 times. Just make sure you keep them well oiled.
June 2009 – It has been over 8 years and still have the original K&N on and it is working excellent, no issues!
