PERFORMANCE DESIGN XS LS3 INTAKE MANIFOLD 112 MM OPENING

Description

The XS Intake Manifold breaks the mold of the existing intake manifold architecture to maximize available space under the hood. When designing the optimum intake runner length and shape the fuel rail gets in the way…so we moved it….inside the intake manifold! After testing all the mainstream manifolds available, our manifold has done what no other did…make horsepower and torque gains on a stock engine with gains increasing as the engine got more aggressive with cam and exhaust upgrades. All other manifolds lost on HP or Torque to make the gain on the other.

The XS intake manifold fits all LS3-style cylinder head ports including L92, L99, L76, L77, LY6, LY2, L20, LMF, LC9, LH8, LH9, L9H and L94.

Even with the additional features and components required for this unique design, Performance Design is able to offer this intake manifold at a price significantly less than existing products on the market.
