Skunk2 is proud to introduce its 70mm Alpha Series Throttle Body for Honda's B-series engines (also compatible with D-, F-, and H-series) in its exclusive, fine shot-blasted surface finish. Skunk2's 70mm Alpha Series Throttle Body is designed to be used with Skunk2's Pro Series Intake Manifolds as well as OEM and other aftermarket intake manifolds for bolt-on horsepower and torque gains by maximizing engine airflow, all at a competitive price.

Skunk2's Alpha Series Throttle Bodies are precision die-cast from high-quality materials and include features previously offered only in our Pro Series line, like countersunk, stainless steel mounting bolts, solid brass throttle plates, fully machined bores, and idle adjustment screws for fine tuning. All Skunk2 throttle bodies undergo an extensive design and testing process to produce a throttle body that doesn't just provide more flow but retains smooth drivability and OEM throttle characteristics.

A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands. Skunk2's Alpha Series Throttle Bodies for B-series engines feature a large, 66mm bore, which results in significant horsepower gains throughout the powerband on heavily modified, naturally aspirated applications and even more on forced induction ones.

Skunk2's 66mm Alpha Series Throttle Body offers Skunk2 performance, industry-leading customer service, and a limited-lifetime warranty policy, all at a price comparable to lesser budget-minded throttle bodies. Unlike the budget-minded throttle bodies, though, only Skunk2 Alpha Series Throttle Bodies ensure precise fitment and the peace of mind of knowing that a Skunk2 representative is just a phone call or email away.
