Trick Flow R-Series single plane intake manifolds for GM LS3 bring the simplicity of carbureted-style aspiration to GM's late model aluminum powerhouse. The intakes are engineered to produce supreme power in heavily modified engines with 3,500-7,500 plus RPM powerbands. Other significant features include A319 aluminum construction, a one-piece spider-type design, high-flow individual runners combined with a raised plenum floor, custom machining for fuel injection nozzles, and extra material for custom porting. The manifold accepts standard Bosch and Siemens type fuel injectors. Overall height to the mounting pads is 6.285 in.
