Porsche 911 Twin Plug 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
• Accepts reusable 964 o-ring style gaskets instead of factory paper gaskets

Valve covers sold as pair. Intended for use with OEM 964 gaskets, sold separately (available here). Includes QTY12 ignition wire clips and screws per valve cover set.
