Product details
Skunk2's all-new K2B Throttle Body Adapter now offers H-series enthusiasts even more flexibility. Thanks to Skunk2's 6061-T6 billet aluminum adapter, any B/H-series throttle body can be bolted onto any RBC-style K-series intake manifold, which is particularly useful when combined with Skunk2s H2K Intake Manifold Adapter. Skunk2's K2B Throttle Body Adapter makes the H2K intake manifold conversion even easier, allowing most B/H-series throttle bodies to bolt directly onto any RBC-style intake manifold, including Skunk2's Pro Series Intake Manifolds. Now reuse your existing B/H-series throttle body assembly for a quicker, less expensive alternative to sourcing a K-series throttle body, MAP sensor and TPS. Each unique, CNC-machined and hard-anodized throttle body adapter features a 68mm bore, recessed holes for easy adaptation, and an 1/8- in. NPT port for even further flexibility. All necessary mounting hardware is included with each adapter, making for an easy installation. Skunk2's K2B Throttle Body Adapters are designed to work with RBC-style manifolds.
