Product Description

The Skunk2 639-05-0100 Billet Hard-Anodized VTEC Solenoid Body is a high-quality upgrade for Honda/Acura B-Series DOHC VTEC engines. Constructed from 6061-T6 billet aluminum and finished with a hard-anodized coating, it delivers both styling refinement and improved durability over the standard cast or stamped covers. This component is especially appealing for engine builds where visible quality matters, whether for performance engines, show cars, or detailed engine bays.

The part is designed to replace the factory VTEC solenoid housing or cover and is compatible with the OEM pressure sensor, gaskets and solenoid internals. Its fitment across B-Series cylinder heads means it fits a wide range of performance Honda/Acura applications (for example the Integra GS-R/Type-R and Civic Si models listed). Before installation, it's essential to verify your engine's head type, VTEC solenoid location and mounting so that this billet component fits correctly.

Installation is straightforward for those experienced with Honda/Acura engine work: remove the original solenoid body/cover, ensure the mating surfaces are clean and flat, replace the gasket/O-ring, install the billet unit with the supplied hardware, torque to spec, and re-install your solenoid internals, sensor and wiring. Because this is a dress-up and durability upgrade, safety in installation (cleaning surfaces, gasket/seal integrity) should be prioritized. Fitment is confirmed for the listed B-Series engines; coverage beyond these assumes compatibility only after verifying engine code and head configuration.
