Trick Flow R-Series 4150 EFI Intake Manifolds for GM LS3

R-Series 4150 EFI Intake Manifolds for GM LS3.

The R-Series intake manifolds by Trick Flow are computer-engineered to deliver carbureted-style aspiration to GM’s LS3 engine. Important 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. These manifolds are intended for heavily modified engines that operate in the 3,500-7,500 plus RPM powerband and will accept standard Bosch and Siemens type fuel injectors. Overall height to the mounting pads is 6.285 in.
