In our shop recently: We put our vertical mill to good use porting a Skunk2 K Series intake manifold for a 74mm throttle body. This manifold is headed for install on a K24/K20, with dyno tuning shortly afterwards.

Our customer Jason S. asked, "Can't this be done on a flap wheel?" The answer is that it is difficult to get the precision to open up the throttle body exactly 4mm with a flapper wheel. We're all about precision!

We are also porting the intake runners.

Here is a close up of the before (right side) and after (left side).

Call or email us to talk about your porting job!

Skunk2 Intake Manifolds

Skunk2 Thermal Intake Manifold and Throttle Body gaskets are designed as direct replacements for OEM gaskets. Skunk2's advanced high temperature thermal polymer material protects against heat soak and maximizes horsepower gains by reducing heat transfer. With the use of Skunk2 thermal gaskets, air intake temps are minimized which provides the your engine cooler air for combustion, and that means horsepower. This and bypassing several heat sources can provide you up to 5% more power.

Skunk2 Racing thermal intake manifold and throttle body gaskets are perfect for your race, weekend warrior and street application.

Features:
- B/D/K-Series Applications
- Direct replacements for OEM intake manifold and throttle body gaskets
- Protects against heat soak and reduces the incoming air temperature before it reaches the cylinder head.
- Reduces HP robbing heat transfer into the intake manifold
- High Heat deflection
