does the 06-07si k20z3 run the same intake manifold as the 05-06 type S?

i heard that the 06-07si k20z3 runs a rrb intake manifold not an rbc

 

no they are different
the si's have a more aggressive (better) im than us 05-06 s'

06-07 si intake mani > any year type-s intake mani

 

The '05-'06 RSX-S still runs the PRC manifold that the '02-'04's run. The K20Z3 motor in the '06+ Si runs the RRB/RBC manifold. Part numbers aside, the RRB and RBC are the same manifold. I actually ordered the Si manifold and it's still stamped RBC on the top.

 

05-06 rsx-s do not run PRC. PRC is the Type R IM. 02-06 RSX-S utilize the PRB IM. the RRB from the 06+ SI and the RBC from the Accord Euro R are the same.
