Overview
Swapping a billet throttle body onto a Honda B-series engine is the job of this Skunk2 part. It is CNC-machined from forged aluminum and hard anodized, and it works with factory manifolds or Skunk2 Pro Series manifolds.
Skunk2 positions this as a bolt-on airflow upgrade built from hard anodized billet aluminum. The fit beyond the B-series is described only as most of the D-, H- and F-series, and no weight or sensor detail is given.
Who it's for
A Honda tuner running a B-series engine, or a D-, H- or F-series engine that matches the description, can bolt this onto either manifold type. Anyone with another make should look elsewhere, and weight-conscious builders will find no weight listed.
Pros and cons
- Billet aluminum construction
- Hard anodized for durability
- Works with factory manifolds
- Covers several Honda families
- Fit beyond B-series stated as most
- Weight not listed
- Sensor details left out
- Port count of two is unexplained
Performance notes
A larger bore passes more air at full throttle, and the billet body is machined to match the intake. The maker ties the gain to airflow through the Pro Series manifold pairing, with no flow or power figures in the listing.
