Overview
Skunk2 machines this throttle body from forged billet aluminum and hard anodizes it black for corrosion resistance. It works with the stock throttle cable and idle air circuit, and the gasket and hardware come with it.
A bigger bore matters on modified engines that need more airflow. The fit list is tied to four K20 engines, and the description mentions a different bore size in one sentence.
Who it's for
Builders with the listed K20 engines who want a bolt-in replacement for the stock body. Owners of stock engines will see little benefit, and later K-series motors need an adapter.
Pros and cons
- Hard anodized billet construction
- Sealed ball bearings
- Works with OEM throttle cable
- Retains the idle air circuit
- Late model K-series needs an adapter
- Narrow engine list
- Bore stated differently in description
Performance notes
A larger bore lifts the airflow ceiling, which only pays off when the rest of the intake and exhaust can use it. The sealed bearings and honed bore keep the plate moving smoothly for naturally aspirated and forced induction builds.

Frequently asked questions
How do I care for the Skunk2 Pro Series throttle body?
The listing gives no care steps. The hard anodized finish is described as corrosion resistant and durable.
Does the Skunk2 309-05-0095 fit late model K-series engines?
Only with a throttle body adapter. The description says it directly replaces the PRB or PRC style body.
Is the bore 74mm or 70mm?
The title and first line say 74mm. One later sentence mentions 70mm, which looks like a typo.
