This genuine 06+ TSX (RBB) intake manifold yields significant torque gains compared to the previous 04-05 TSX (RAA) intake manifold. Gains can be experienced when directly installed and especially when tuned on certain K24A engine setups. May required 06+ TSX throttlebody which is 2mm larger than 04-05 TSX throttlebody.

Note: This manifold is specifically designed and will only fit onto all K24A (TSX/CRV/Element) and 06+ Civic Si heads.

This manifold is NOT a direct bolt-on for K20A/A2/Z1 series engines; modifications need to be made in order to fit properly. Direct fitment for 06-11 Civic Si.

Note: this manifold does not come with the injector base portion of the manifold.
