HONDA J35Y Ridgeline Throttle Body. This brand new 2019 Honda throttle body is an excellent upgrade over the FN2 OEM throttle body. It features a 12mm bigger (over OEM) bore - same as the original J37 but cheaper! You will need to port match the RSP and RRC inlet manifold to 70mm otherwise a bottle neck will occur. Complete with plastic T-piece as this throttle body features 1 less vacuum source. The ultimate DBW genuine Honda OEM throttle body.
