This manifold is the result of over one year of development and testing and has proven to provide significant increases in power. In direct comparison dyno tests against a factory LS6 intake manifold, the Typhoon produced 17.7 more horsepower* at 6,200 rpm. It also makes more power and torque at low and mid-range engine speeds than other aftermarket manifolds. This design features a larger plenum volume, which makes the manifold suitable for larger displacement engines and boosted applications. The manifold has nitrous bosses positioned on the port runners.

The 52060 comes with an 85 mm inlet than can be enlarged to 90mm. Professional Products offers 80 and 85mm throttle bodies for LS1/LS6 applications.

The manifold kit includes high volume fuel rails with stainless steel mounting brackets, stainless hardware, and a -6 AN stainless braided crossover hose. Additional fittings are also supplied that allows connection to the stock fuel inlet line.
