K&N filter set up and throttle body spacer off TJ

I have a K&N filter set up and TBI spacer off a TJ that I was thinking of putting on my '93 YJ.....a) will it fit? and b) is it worth the effort doing the retrofit.

most arguments that I've seen against that set up is cost.....I already have it, so it would be free besides a little wrenching

Thoughts?

Reports I've seen say the throttle body spacers do nothing, not worth the work. If you're going to keep the K&N I would suggest a pre-filter over the K&N. K&N's are good for letting air in, but not so good at keeping fine dust out. I run a Airraid pre-filter over my K&N, cheap insurance.

Jeep intakes are quite good. K&N filters let dirt in. Spacers are a waste of money. With the hundreds of millions spent by R&D, the factory would have built a slightly higher intake.

The best air filter (in this test) is stock or Baldwin

Maybe if you were drag racing...

Tj's have the intake mounted on the passenger side, while YJ's are on the driver's side. If you can get around the relocation, I am sure it can work. The MAF sensor will not be needed from the Tj

Nothing wrong with jeep filters, but the placement of the intake is terrible for water crossings. The intake is in the grill by the headlight where your bow wave would be in deep water. I went with a air-tube and K&N not for better filtering, but for water crossings. I can go through water that comes over the hood because the water level in the engine compartment stays lower if you keep moving. The pre-filter helps the K&N a lot, it's what we use on quads which which go through a lot more dust and sand than most jeeps breath.

I rained here, there was a puddle with a few inches of water. I went around it

I could go around the water crossings too, but like any little boy, put a puddle in front of me and I'm going through.....the deepest part

Around here the yuppies in their 4 door JKs will do everything short of causing a head on collision to avoid puddles on the street
