We are currently building a 20B intake system similar to our proven 13B.
Lower intake manifold comes with its own 8AN ORB fuel rail( 6 injector, 1 more injector per rotor than OEM). Lower intake manifold is O-ringed at UIM flange, no emissions ports, off road/compeition use only.
Lower intake manifold will sit at OEM FD height( lower than the OEM 20B) Intake runners will be slightly larger than OEM( 2mm), and will be shifted forward 25mm( to accomdate equal length runners).
