I just purchased a rev up and while i inspected it before buying (3mo ago) i noticed it had a K&N drop in and a borla catback as well as a motordyne plenum spacer and i just assumed that was all. well after installing the Momentum Performance cold air and changing the plugs i noticed a open/closed valved on a hose going to the throttle body and later learned that hose was to heat up the throttle body and keep it from freezing up but here in lousiana its never that cold and i guess the guy thought he'd close it off and make the intake temps 'therioeticaly' cooler.
Well this got me to looking and since the car was tastefully modded (besides the borla lol) i got to looking at the lower plenum and saw its not the same colo/finish as the upper.

Is there any way to be positive that i have a mrev w/o taking the upper plenum off?

 

Sends pictures to Tony@Motordyne he can confirm for you.
