Specifically engineered for Ford Sierra Sapphire Cosworth 4WD T34 models equipped with the original dump valve, this PAFCLASSIC® Silicone Boost Hose Kit replaces ageing factory boost hoses with reinforced silicone components built to cope with the demanding environment of a turbocharged Cosworth engine.
The kit contains 3 high-performance silicone boost hoses manufactured using premium 3-ply silicone reinforced with polyester textile fibres. This advanced construction delivers excellent resistance to sustained boost pressure, elevated engine bay temperatures, and long-term material fatigue, helping maintain a dependable and efficient boost system throughout the life of the vehicle.
Designed as a direct replacement for the original hose set, installation requires no modifications while ensuring an accurate OEM-style fit. Whether replacing worn factory hoses, restoring a cherished Cosworth, or upgrading a performance road car, this kit provides a reliable solution with a premium-quality finish.
Manufactured in England to exacting standards, every PAFCLASSIC® hose kit is available in a choice of colours, allowing you to personalise your engine bay while retaining the authentic appearance and fit expected of an original-style installation.
