I don't know if there is already a thread on this BUT has anyone installed one of these on a 4.0L? If so have you noticed a difference?
Thanks
David...
The simple answer is "no". But that doesn't really answer
your question.
Throttle body spacers (TBS) can/may help some engines that have
carburetors or throttle body injection. The 4.0's in 94 (I'm guessing that's what you have) have neither of those from what I have been told. They have
multiple injectors on the intake and a TBS would not help and could actually hurt
performance and mileage.
A cold air intake may be a better choice if you don't allready have one. Plus they make it sound like you're going faster :wings:.
