So I have an 07 HR Z and it seems there aren't too many aftermarket plenum spacers for the HR engines... Now I have a bassani exhaust on its way and was wondering if the HR engine benefits from aftermarket dual intakes more or from plenum spacer (if there are any out there). I was going to get the motordyne plenum spacer but was informed it was only available for the 03-05 Zs... Would the dual intakes net me the same hp a plenum spacer would offer? For those who own the HR Zs and have upgraded their intakes, are they worth the $?

Dude searching would of given you the answer. Yes, long tube intakes (stillin & injen) have shown some gains on the dyno, compared to ram air intakes. Get the plenum out of your head because No one has ever tried to make one for the HR, as far as i know of. HMm search more and you get your answers in more detail.

+1 HRs do not need spacers

if by not too many, you mean 0, you are correct

there are no spacers for HR's because HR's have a totally different intake setup vs DE's, which eliminated the need for a spacer
