GM intake manifolds
availability
Genuine GM and Chevrolet Performance intake manifolds, gaskets and throttle body adapters for the LS, LT, small block and big block engines.
What is here
LS3, LS7 and truck intake manifolds, the LT1 and LT4 manifolds and supercharger lids, Chevrolet Performance aluminum manifolds for small block and big block builds, and the gaskets and hardware for each.
Before you order
LS manifolds differ by port shape: cathedral, rectangular and the LS7 raised port are not interchangeable. Match the manifold to your heads and order the gasket set and throttle body seal with it.
Why buy it from a GM dealer
Factory manifolds are tuned for the engine they fit and work with the stock calibration, so the swap does not need a retune.
