Is there any gain to puting a '06 rev-up lower plenum on an '03 motor?? I'm buying the Kinetics upper plemun, and was thinking a lil down the road of adding the rev-up lower plenum if it would be worth wile. Will i loose low end torque?? Thanks!

 

anyone??

 

no gain

 

Yeah that's i figured. Seems like if it helped everyone would be doing it.

 

Dont do it. I was running the 05 Track lower plenum(same as 06) and it killed my low end tq and mid range power and added a little top end. Switched to a spacer and got all of my low end back with top end. Go with a 5/16th spacer.

 

Cool ok thanx!

 

+1. 287hp lower plenum produces more tq and midrange power. Go with a MD 5/16th spacer and call it a day.
