The TJ needed to have it's air filter replaced and I wanted something with more flow. I decided to go with a setup that I used on my 2.5L YJ. I made the filter housing on that one though and used a rectangular factory filter, because it was right on top of the TB it tended to get dirty just in a little circular area right in the center of the filter. I figured I would try an oldschool round air cleaner this time, but I had fitment problems. This one fit perfectly.
It's for a four barrel, so it has the 5.125" carb hole in it. I made a mount from a piece of 3" tubing and a donut shaped disc that adapted the tubing to the carb hole, then welded it to the bottom of the cleaner. It's got a rubber base and two set screws holding it on the TB
It looks pretty good and sounds like I've got a demon trapped under the hood when the throttle is opened up. It's a foam element, so it can be washed with soap and water. It made a bigger difference on this engine than it did on the 2.5L. What do you think I should put in the space left from the factory airbox? Storage? Air tank?
The air cleaner was $20.00 and I already had the other materials, so it was half the price of a K&N drop in filter.
