FAQ:

Q: Can a LS6 manifold be swapped with an LS1 manifold?

A: Additionally, the LS6 intake manifold is also a fan favorite for manifold swaps as well. The LS6 intake and manifold bolts directly onto the LS1 and provides power gains of nearly 25whp and 20wtq.

Q: Is the Dorman LS6 intake manifold the same as the LS2?

A: Dorman says it also has a 90mm LS2 intake in the works that will be a true performance upgrade for the LS1/LS2 manifolds and an improvement on the original LS6, too. The bottom line is less scrambling (and less money) for LS enthusiasts looking for that quick LS6 power upgrade.

Q: Is the Chevy LS6 intake a good intake?

A: The LS6 intake is actually built really well from the factory and has plenty of air flow. It is actually so good that a ton of LS1 owners swap LS6 intakes and intake manifolds onto their cars, in favor of aftermarket brands.

Q: What kind of throttle body does Dorman intake manifold use?

A: The Dorman LS6 replacement intake manifold (denoted by the red line) delivered nearly the same power as the original LS6 (blue line). Both the original GM LS6 and Dorman intakes were mated with a 78mm throttle body; the FAST manifold (black line) used a 90mm throttle body for its test.
