The Hybrid Racing ZDX throttle body adapter allows you to bolt a throttle body from an Acura ZDX engine onto your 2006-15 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 30 minutes. Works with RBC and RRC intake manifolds.
