Restore the critical cooling airflow to your 928's engine mounts.
Introduced in 1987 alongside the S4’s aerodynamic belly pan, these specialized air ducts are vital for managing engine bay temperatures. By directing high-velocity air from the underbody directly onto the engine mounts, they prevent premature heat-soak of the engine mounts - a common issue in the hot, cramped engine bay of the 928.
For years, these ducts have been "unobtainium," leaving owners with overheated engine mounts. Sirius Fabrications has solved this by painstakingly reverse-engineering the original factory geometry to produce a perfect-fit replacement that exceeds OEM standards. Many have tried to recreate these with varying levels of success, but nothing like this has been available until now.
Available in three tough materials using two 3D printing technologies: Fused Deposition Modeling (FDM) and Selective Laser Melting (SLM).
Carbon Fiber Reinforced Nylon (FDM): Lightweight, extremely durable, and heat-resistant. Ideal for those seeking a factory-plus look with modern composite strength. The PA6CF material has excellent corrosion resistance (fuel, oil, hydraulic fluid etc) and can withstand up to 200 deg Celcius before deforming.
316L Stainless Steel (SLM):For the ultimate in longevity. These are solid metal components with incredible corrosion resistance. Please allow 10 to 15 business days lead time.
Aluminium (SLM): Provides high strength-to-weight ratio and excellent corrosion resistance. Please allow 10 to 15 business days lead time.
Key Features:
Perfect Fitment: Painstakingly reverse-engineered in CAD using original reference units to ensure 100% compatibility with the factory 1987+ OEM, and aftermarket aluminium belly pans. Countless prototypes (the grey ones in the photo) were printed and tested until the fit was millimetre-perfect.
Engineered for Heat: Materials selected specifically to withstand the harsh environment of the 928 engine bay.
NLA Solution: Replaces Porsche parts that have been out of production for decades.
