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 162LB-FT 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!

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.
