The Hasport K-series intake manifold adapter makes it possible to bolt a K20A PRB/PRC style intake manifold onto any K24A (incl. TSX), base model RSX, and 06-11 Civic Si (K20Z3) engines.
This manifold adapter separates the water neck from intake manifold similar to how the RSX Type-S intake manifold flange and water neck is. This makes it a plug n play affair when swapping a PRB/PRC style intake manifold(s) to all K24A, K20A3 (base rsx), and KZ203 heads.
