This Skunk2 throttle body helps move more air through the head by using a larger diameter opening than stock. It is strongly suggested that the throttle body be upgraded with the intake manifold if you are upgrading to an aftermarket intake manifold. The skunk2 throttle body is one of the most high quality pieces on the market. We strongly suggest the use of the Skunk2 Throttle Body for an easy bolton power adder.
The Alpha throttle body is less expensive than the pro-series throttle body because it is made by die casting instead of billet machining.
Skunk2 has been on the market for years and has earned their reputation for making high end engine components. Skunk2 offers top of the line Cams and Valvetrain at a reasonable cost.
