Overview
On a modified Honda engine with higher airflow demands, this Skunk2 throttle body replaces the factory unit with a CNC machined billet body. Sealed ball bearings and a machined brass plate are described as giving smooth operation.
Skunk2 aims this at builders running naturally aspirated or forced induction setups that outgrow the stock bore. The condition that matters is the larger diameter, which calls for the matching Skunk2 manifold or flange work.
Who it's for
A tuner with a manual Honda in the listed engine families who is also fitting a matching manifold will find the throttle body and its hardware ready to go. Anyone wanting a simple swap on a stock manifold should choose a smaller unit.
Pros and cons
- Billet aluminum, hard anodized
- Sealed ball bearings
- Works with the OEM throttle cable
- Gasket and hardware included
- Manual transmission only
- Needs matching manifold or flange work
- Not for D-series down-flow manifolds
- Larger bore needs supporting parts
Performance notes
A larger bore passes more air on engines that have been modified for more airflow, and the honed bore and ball bearings are meant to keep throttle movement smooth. The listing says the oversized diameter requires the matching manifold flange, so the result depends on that part of the setup.

Frequently asked questions

The title lists D-series engines, but the notes say it is not compatible with D-series engines using down-flow intake manifolds.
Can the Skunk2 309-05-0050 be used on an automatic car?
No. The listing says manual transmission only.
