Hello,

Another member of the board (on some other section) shared this link:

http://go.jeep-xj.info/HowtoIntakeManifold1.htm

Has anyone used the newer larger/rounder intake manifolds on the 4.0L YJ? The link states gains in lower rpm torque at the cost of some high rpm response. The part about a Jeep engineer stating an improvement of 15hp caught my eye. It's just that we've all heard about so many possible hp gains that end up nowhere that I wanted to double check with you guys.

I was just curious to know what if any your experience with this mod is. I do like to rev my engine so maybe this would be better for rocks than mud/street.

Thanks,

ROD
