I'm sure at some point the added capacity will not do much more for power, but I'm wondering if anyone has done or considered doing all three together and their results. I searched and found people matching up 2 of the three, but none with all three. If I missed it, sorry, but point me in the right direction.

 

do it and post before and after dyno's.

 

better yet, convince the guy who's currently doing a "shootout" between the two parts

Independent testing shows that aftermarket upper plenums are a poor option. And you are correct: you get to a point where tall adversely effects performance. If taller was better then someone would give us a 3-inch spacer. It is not going to happen.

 

Am I mistaken ???? The Kinetix plenum replaces top and bottom stock plenums so a plenum spacer cant be used since it goes between bottom and top stock plenum

 

Sorry --I was mistaken ---I had forgotten that Kinetix had the top Plenum assy. ---I was thinking of the Extreme plenum they make that ---Really from what Iv seen it mostly show and no go
But this is a situation I believe that More is NOT better.
But --give it a shot,, u would have to be very careful u add the right length spacers between top and bottom plenum ( 6 long center bolts) to compansate.
