Apologies...Barry who?

I guess the main question is the necessity of using this on the new motor with the new RARE manifolds. Obviously wouldn't be used if I had went the header route. Would also mean backing out the 2 ARP bolts already installed for mounting (and if anytime I wanted/needed to get at the manifolds).

How many of the guys using the RARE manifolds opted to buy/install these? I am assuming the only purpose is to preheat air and route to the air cleaner for emissions purposes? No perceived performance or functionality gain?
