This post is about higher flowing lower intake manifolds . A friend of mine turned me on to a discovery he made . Apparently on the 2016 and up Grand Cheerokees 3.6s and all the new vehicles with start/stop technology , they went with a different intake manifold that works on our cars. Its also part of the Pentastar Upgrade Engine (PUG) that used in the 2018 JL's.
I'm running it out of the box on my car and it picked up mid-range and top end. I could feel the power coming on much sooner .
In this picture , the top is the manifold out of the box. The bottom picture is a fully ported stock manifold . See how much bigger then port is ?
Part number 05281803aa is the new design and it's pretty inexpensive .
It runs 104.78 on some sites.
What about everyone else ?
