RBC Intake Manifold to 70mm J37 (ZDX/ MDX) Throttle Body Adapter

Honda's RRC and RBC intake manifolds are among the best-flowing K-Series manifolds Honda offers, which makes RBC/RRC manifold swaps a popular upgrade for engines equipped with less desirable manifolds like the 2012–2015 9th Gen Honda Civic Si, 2013–2015 Acura ILX, 2009–2014 Acura TSX and 2008–2012 Honda Accord. These swaps often require a throttle body adapter. PRL machines this billet adapter from 6061 aluminum to seamlessly mate a 70mm ZDX/MDX drive-by-wire throttle body to the manifold, adding airflow while retaining OEM reliability and drivability at an affordable price.

The adapter seals to the intake manifold with an O-ring and to the throttle body with an OEM Honda gasket. A 1/8" NPT port and 90-degree fitting retains the factory EVAP purge.
