LSX-LS3 4-bbl Intake Manifold

119354471 Chevrolet Intake Manifold

Dual-Plane, Standard Deck

The best way to feed an LSX engine is with air channeled through a Chevrolet Performance LSX intake manifold. They’re designed to match the performance capability of our LSX heads and big-displacement rotating assemblies. LSX intake manifolds have a high-flow, spider-type design and are made of lightweight aluminum. They’re cast with plenty of material for builder-specified port work; and the flanges are a minimum of 0.5″-thick to accommodate machining.

Additional features include:

  • Standard-deck and tall-deck versions
  • Natural finish with LSX and GM logos
  • Injector/nitrous bosses cast in place
  • Comes with installation hardware
