The Pro-Flo XT LS1 EFI intake manifold is engineered with a large plenum and tapered runners to deliver maximum horsepower and broad torque band throughout the rpm range (1500-7000 rpm). Features include a 90mm throttle bore opening and 2.75" port exit height. This manifold produced 30 more horsepower over a stock LS6 manifold at 6500 rpm. Accepts Pro-Flo XT throttle body #3869/#38693 or adapter #2737 and standard LS1 throttle bodies. Compatible with LS1 Fuel Rail Kit #3629 (sold separately). The Pro-Flo XT LS2 intake manifold offers the same performance qualities as the LS1 version and is machined to accept OE or equivalent LS2 throttle bodies. Aesthetics were also a major consideration in these designs by offering custom looks and choice of natural cast aluminum or black powder coated finish with contrast machined surfaces.
