Title: intake manifold question
Post by: TenTanToes on May 13, 2009, 02:01:04 PM

Hello all, a quick question about intake manifolds.  I know on the 4.0 that the 99+ IM has curved runners as opposed to the older style with almost right angles.  Did they happen to make a similar change for the 2.5?  Thanks for your input!

When Jeep changed from Throttle Body Injection to the current port injection, they changed the intake manifold to the curved runner style.  Not sure of when that was, '91 maybe?

No change in the '91+ manifold that I'm aware of.
