hey gang anybody replace their plenum from vq35de to high rev and seen gains? with or without motordyne spacer?

thanks

 

search bro.... there are many many threads on this topic.

 

Hr is completely different
You need to edumacate yourself

 

I'll give you the most simple answer.

What you're asking makes no sense. There's more to the rev-up than just the plenum.

If you have the DE, you're best and only mod choice is the MD spacer... That's it.

On a side note. The HR is NOT found on any G35 coupe. The HR is a whole different engine found in the G35 sedans of 07-08.
What you're referring too is the REV-UP.
