Skunk2 is proud to introduce the 74mm Pro Series Throttle Body for Honda K20A/ K20A2/ K20A3/ K20Z1 engines found in the 2002-2005 Civic Si and 2002-2006 DC5 Base & Type-S chassis.
A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands and the Skunk2 70mm Pro Series Throttle Body delivers! Sealed ball bearings, a precision machined throttle plate and a honed oversized bore insures smooth operation on the most aggressive naturally aspirated and forced induction applications.

You know that a larger bore throttle body will help improve air flow. But when the intake manifold's opening isn't as large as the new throttle body's bore (it almost never is), performance gains will be small. Unlock your engine's full potential when swapping to a larger bore throttle body. Learn how to properly port-match your intake manifold and remove the restrictive step that's created when the throttle body and intake manifold openings don't match up.... [Read more]
Finding power gains among Honda K-series engines is all about combination. A simple manifold swap on one engine may likely produce entirely different results on another. However, one thing most every K-series engine can benefit from is a larger throttle body. It a relatively simple and inexpensive bolt-on that yields impressive power gains under the right circumstances. Skunk2's goal was to design a throttle body that would perform well on highly modified engines as well as stock ones. As such, Skunk2 offers two: its 70mm Pro Series Throttle Body and its 74mm Pro Series Throttle Body. Find out how they fare against one another as well as against the factory K20A2 throttle body....

Skunk2 is proud to introduce its 74mm Pro Series Throttle Body for Honda K-series enginesâ€”the biggest K-series throttle body you can buy. Skunk2 Pro Series Throttle Bodies are designed to be used with OEM Acura DC5 (PRB) or Skunk2 Pro Series Intake Manifolds for bolt-on horsepower and torque gains by optimizing engine airflow (other applications, including â€™06+ Civic Si RBC manifolds, require adapter plate)....
