Triebwerk Valve Cover Set made of precision-machined aluminum

Our high-quality, CNC-machined aluminum valve covers take durability and aesthetics to a whole new level. They replace the original magnesium or plastic covers, offering significantly improved stability and sealing performance—even under demanding operating conditions.

• High-strength aluminum alloy: Offers superior stiffness and thermal resistance compared to OEM parts.
• In-house CNC precision machining: Guarantees a perfect fit and absolute flatness of the sealing surfaces for optimal seating; this reliably reduces the common problem of oil leaks at the valve covers.
• Improved heat dissipation: Aluminum dissipates heat significantly better than magnesium or plastic—which ensures more consistent temperatures in the engine compartment.
• Corrosion-resistant & durable: Features a black or clear anodized coating; can be customized (logo, color, engraving).
• Sporty look: Sleek, technical design—ideal for performance projects or restored collector’s cars.
• Plug & Play: Can be installed on all Porsche 964 and Porsche 993 engine variants without any modifications.
• Perfectly prepared: Mounting points for individual spark ignition coils.

Triebwerk valve cover

Our new valve covers for all 911s of the 964 and 993 generations. They replace the old, often corroded and warped original covers. Background: After roughly 30 years of service, they rarely look presentable anymore. This is due in no small part to the magnesium content in the original alloy.

In contrast, at Triebwerk we use lightweight, high-strength aluminum with high tensile strength. In addition to precise processing and sealing, this also offers maximum durability: our valve covers do not warp, they remain oil-tight and attractive. To improve the heat department, we have provided them with cooling fins so that you can see and experience the subtle difference straight away.

In addition, our valve covers allow you to securely bolt on single-spark ignition coils as well as the original spark plugs.
