The K20A/A2/A3/Z1 Throttle Body To RBC/RRB/RBB Intake Manifold Adapter provides the SOLUTION for directly bolting up a 2002-2006 RSX-S/ITR or 2002-2005 Civic Si/CTR throttle body to an Accord Euro R, 2006-2009 Civic Si, or 2004-2005 TSX intake manifold.
Ease of fitment has been confirmed for the following vehicle/engine/mount combinations:
- 1992-1995 Honda Civics equipped with a K20 engine and Hasport EGK1 engine mounts
- 1996-2000 Honda Civics equipped with a K20/K24 engine and Hasport EKK2 engine mounts
- 1994-2001 Acura Integras equipped with a K20 engine and Hasport EGK1 engine mounts
- 2002-2006 Acura RSX-S/Honda ITRs with a K20 engine and all available engine mounts
Other chassis, mounts, and engine combinations can still utilize the RBC intake manifold; however, clearances between the radiator support, radiator, and hood may need to be addressed. For example, a 2002-2005 Honda Civic Si/CTR just needs some minor trimming of the upper radiator support in order to fit an RBC manifold into its chassis.
Are you desiring to make the full potential of your K-Series engine with a cost-effective, well-engineered, Honda factory intake manifold? We tested the new RBC (2006-2009 Civic Si) intake manifold (Honda Part #: 17100-RRB-A00) and were able to make 230whp and 160tq out of a completely internally stock K20A2 engine. For a total cost of under $300 USD (Karcepts K20A/A2/A3/Z1 Throttle Body To RBC/RRB/RBB Intake Manifold Adapter, RBC Intake Manifold, and miscellaneous gaskets and hoses), this is by far the best “BANG-FOR-YOUR-BUCK” power upgrade!
All mounting hardware is provided for attaching the adapter to the intake manifold and the throttle body to the adapter. Two rubber plugs are additionally included in order to plug the unused MAP sensor port located on the RBC/RRB/RBB intake manifold as well as the ability to plug the EVAP Purge Control Valve port if desiring to do so in order to gain additional hood clearances.
