Key Features & Specs:
Fitment:
The Skunk2 90mm Throttle Body Adapter (309-05-0015) is a precision-engineered solution designed to expand compatibility between throttle bodies, intake manifolds, and cylinder heads across multiple Honda platforms. CNC-machined from high-quality 6061-T6 billet aluminum and finished with a durable hard-anodized coating, this adapter allows you to run larger throttle bodies and optimize airflow for high-performance applications. It enables the use of K-series intake manifolds on H22A cylinder heads, adapts B/H-series throttle bodies to RBC-style K-series manifolds, and supports Skunk2 Ultra Race intake manifolds. Ideal for engine swaps and custom builds, it improves clearance and unlocks the performance benefits of larger plenums and shorter intake runners.
