Acura ZDX Throttle Body & Adapter Combo Kit - RBC / RRC / R40 / CT-E
The Acura ZDX Throttle Body Kit is the perfect addition for anyone looking to go with an oversized throttle body. This 78MM Throttle Provides ample room for intake volume, its a good 15MM larger than the oem throttle body and even 10MM larger than the J35. Due to its size, this throttle body needs an adapter to work with a few different intake manifold setups. We provide that in each kit. RBC aka RRB Manifold is the one from the 06-11 Honda Civic Si. The R40 is the one from the 2012+ Honda Civic Si. The RRC is the one from the Japanese Type-R or FD2 Manifold. Then finally if you are running a CT-E, Comptech, CT-engineering manifold aka supercharger inlet. Then you will want to designate that option for the correct adapter.
