The Hybrid Racing ZDX throttle body adapter allows you to bolt a throttle body from an Acura ZDX engine onto your 2006-13 Civic Si. The ZDX throttle body has a larger bore than your stock throttle body allowing your engine to make more power. Expect to pick up between 2-10hp depending on the other modifications you have installed. We recommend port matching your intake manifold to 70mm and tuning with a Flashpro to maximize power and driveability. The kit comes with everything you need to complete the install in less than 30min.
Works with RBC and RRC.
Includes the following:
ZDX to RBC throttle body adapter
ZDX thermal gasket
RBC thermal gasket
Bolts and washers
Vacuum fitting for purge control valve solenoid
Applications: 2006-13 Civic Si
