Clean up your engine bay and solve clearance issues with this billet PCV valve extension adapter designed for H-series and F-series DOHC VTEC engines. This simple yet effective upgrade relocates the PCV valve to a more practical position, providing additional clearance and smoother hood closure—especially on modified or swapped setups.

Why This Upgrade Matters:

On many H-series and F-series engines, the factory PCV valve location can interfere with hood clearance or surrounding components. This extension adapter repositions the PCV valve toward the rear, improving space management while maintaining proper crankcase ventilation.

Key Features:

• Improved Clearance – Relocates the PCV valve to the back of the adapter for easier hood closure.
• Billet Aluminum Construction – CNC-machined from solid 6061 aluminum for strength and lightweight durability.
• Precision Fitment – Designed specifically for H-series and F-series DOHC VTEC engines.
• Leak-Free Sealing – Includes high-quality O-rings for a secure, reliable seal.
• Anodized Finish – Corrosion-resistant surface built to last under engine bay conditions.
