Any decent gains to be had upgrading from a 00 civic si's stock intake mani to the jdm itr?

Thanks


Oh yeah and whats the going price on the mani?

 

From lookin at youe signature, I don't forsee any reason why you'd gain anything Skunk2/blox are based off of the jdm itr manifolds and without any sort of header or even throttle body I doubt anything will be seen except maybe 1-2 hp if that

 

You will lose power unless you add decent cams, it will not be worth it on your engine.
