Any substantial power gains? How does this compare to running just the 5/16 plenum spacer? 1 step above?

 

i have 1 i traded for my 5/16 spacer power feels the same and it dyno'd just about the same too . it will make your car run alot cooler prevents heatsoak and looks nicer than the oem plenum lol just dont over torque on install if you do kinetix offer a life time warrenty on these too

 

Thanks for clearing that up kristinavq...i am no longer selling this...had to keep it due to the other plenum that i was gonna buy became unavailable...sorry folks..i will update this if any changes occur...
