Product Description

The Skunk2 307-05-9055 Ultra Series Intake Manifold is a high-performance race intake designed to dramatically improve airflow on Honda B-Series VTEC engines. Featuring a modular 3-piece construction, 3.5 L plenum volume, and 90 mm throttle body flange, this manifold is engineered for builds aimed at significant power increases in naturally aspirated and forced induction setups.

Constructed from high-grade 356 aluminum and CNC-machined for precision, the manifold's tilted and tapered runners with raised 87 mm velocity stacks optimize airflow for high RPM performance. Multiple accessory ports and provisions for secondary fueling make it ideal for advanced tuning and race builds.

This Ultra Series intake manifold is intended for motorsport and high-output applications - not stock street use. Proper installation often requires compatible throttle body hardware and tuning to realize its full potential. Always verify fitment and supporting components before installation.
