L82 and LG8 3100 Intake Manifolds

If you own a 1994-1999 3100, please read this article before purchasing a manifold set.

The WOT-Tech Competition Series represents the best of what we have to offer, with fully ported runners and the best runner taper and port texture available anywhere. Flowbench designed as a complete system from head to throttle body for the best performance at any level. 

Our Sportsman Series use the same port shapes as the competition, but with an emphasis on blending instead of completely reshaping the entire runner path. The first 2" is blended to the rest of the runner, where the majority of flow is improved.

If you are not aware of the differences between certain years, please check the following article before selecting the manifolds you want.
