Does Anybody Have Any Experience With The Combo? I Have A Sedan With 5/8" Spacer. I Want To Pair It Up With The Kinetix V4 Plenum I Have In The Garage. Im Planning On Taking My Engine Cover Off Too, For Cooling Purposes. Please Help!!!

 

I personally wouldn't do that..since the increased upper plenum volume
might decrease the air flow speed...
simple fluiid mechanics principle..
However, if you want the best cooling results.. I would say..why not
stick with ur 5/8" MD spacer + a Iso thermal kit?

It has been working great for me at least

Cheers,
Godmans
