Intake Question

If I put a later model cone style K&N filter setup on my 90 YJ 2.5L with TBI will it cause it to run lean? Just wondering, looking for some more umh as all the 4 bangers are!

It shouldn't run lean it will get more air. If you need more umph for your 2.5L go here

Thanks for the response! My only concern is that it is a Throttle Body Injected engine and that the fuel injector is also inside of the throttle body. I know that 89 and 90's were made this way, changed to port injection in '91. I just wanted to make sure that this mod wouldn't cause the mixture to run off because of the fact that its getting more air. I know the fuel injector pulses in response to the position of the TPS that's why I was concerned that the engine might run in a lean condition. Has anyone done any mods with the TBI 4 bangers, anyone else curious? I wish that I would have found a 91, it would make this mod so much easier!

I totally forgot about that the 90's have TBI (the 3 bolt as opposed to the 4 bolt ones on MPFI) The ones I have are all for MPFI...

Hey, I have a 4.0 liter TBI throttle body from an 87-90 Cherokee. I mistakenly bought it to put on my '94 not realizing there was a difference. It's just sitting on a shelf gathering dust. It doesn't have any sensors, and I'm not sure if the injector is the same but you could find out from a dealer. I just want at least some of my $$ back out of it. Find out if it will work then email me if you want it. I'll sell it for $20 plus shipping from 64114. I also get cheap shipping through work. Same goes for anyone else needing a TBI throttle body.

Thanks,
Tommy

The engine's computer should re-adjust when it senses more air intake, shouldn't it? I would say it will adjust the fuel to make the right mix. Shouldn't be a problem.
