Professional Products LS1, LS6 and LS2 Intake Manifolds
This unique new design features a larger plenum volume than stock or aftermarket manifolds, somewhat similar to the 2006 ZO6 manifold. This larger volume is particularly suited to big inch engines but extensive dyno testing on a stock LS1 Intake Manifold also shows substantial gains, especially in the mid-rpm ranges.Tested primarily against a leading aluminum aftermarket manifold that is similar in design to the LS6 Intake Manifold, the Professional Products intake showed equal power on the top end with an additional 12 to 15 hp in the 3,000 to 4,000 rpm range. It was also tested against a factory LS6 Intake Manifold and produced an additional 17.7 hp at 6,200 rpm on an engine dyno.
All versions of the Intake Manifold come with custom fuel rails, a stainless braided -6AN crossover hose, an inlet fitting that connects to the stock fuel line, stainless steel fuel rail mounting brackets, and all stainless attaching hardware. Note that early (1997-'98) LS1's that had a fuel pressure regulator mounted on the fuel rails will require optional #52160 regulator kit which includes a 25 to 75 PSI EFI adjustable regulator and additional fittings to incorporate the regulator into your fuel system. All three styles of the LS Intake Manifold also include nitrous bosses suitable for drilling and tapping for nitrous nozzles. Note that there is only space for a single tapped hole per port.
