Porsche 993 Lower Valve Cover (Billet Pair)

Replace your leaky Porsche 911 valve covers in style with these billet aluminum replacements. Stimmt Works covers were engineered to be a direct replacement for OEM valve covers with significant rigidity improvements and enhanced gasket fitment.

Our valve covers offer various improvements over OEM and others currently on the market:

• Slightly enlarged spark plug bores to allow for both custom coil-on-plug setups and factory ignition
• Optimized gasket channel depth for ideal gasket compression

Valve covers sold as pair. Intended for use with OEM gaskets, sold separately (available here). Includes QTY10 ignition wire clips and screws per valve cover set.
