Benifits from an intake spacer?

+1

There can be some benefit if using a phenolic spacer as it may isolate the upper intake a little from engine heat, but the difference will be negligible. FWIW, I'm running taller valve covers to clear my rockers, and I'm not running a spacer with no clearance issues.

anyone know if a 1/2in spacer on a cobra intake will clear the stock hood??

frpp makes a .5 inch gt-40 spacer. whether that will clear or not, i don't know. maybe if you cut the hood a bit

They also make a 3/8 spacer if you are nervous about hood clearance.

I use one to keep my intake up off the plug wires for easier access to some stuff. Otherwise I wouldn't use it at all. The intake is still lower than the STB I have so I would bet the stock hood will clear a 1/2" pretty easily without the insulator in...
