So i was traveling the automotive world and i came accross interesting information, apparently the F23 intake manifold yields gains upwards of 10HP on F22B motors. Honda Tech folks claim 30hp gain from F23 intake manifold, H23 throttle body and tune, as to whether this is true or not i am uncertain but one must admit that if those gains are proven then it is a pretty good cost effective mod.

Yeah, it's pretty much the same as CB guys swapping an H23 throttle body and upper intake manifold to the F22A6 runners on any F22A cylinder head. The added HP is based on the larger plenum supplying a larger volume of air at initial cylinder filling and the larger throttle body and shorter runners for HP in higher RPM ranges.Last edited by GhostAccord; 02-22-2017, 07:16 PM.
