Throttle body swap
When you put a 4.0 TB on a 2.5L, do you use the same sensors that are on the 4.0 TB? Do you have to swap them out? Or just install the 4.0 and go?
Thx for any responses

need to you use the sensors from the 2.5L TB.

I used a TB from a 5.9L Dodge on my 01' Laredo 4.7L. It was a plug and play install. Went from 60mm to 70mm. When you get done let us know how you like or don't like it. And I will let you know how mine works.

Sounds good, thanks for the info

Jp Magazine tried installing a 4.0L TB onto a 2.5L engine several years ago and noticed no performance gain. In fact, they commented there might have even been a little bit of a loss in performance.

IMO throttle body swaps and trottle body spacers are wasted money.

I just bought another jeep and it has a TB spacer installed. It is coming off!
