Ford Sierra Cosworth 2WD (with Original Dump Valve) Silicone Boost Hose Kit

Designed for the Ford Sierra Cosworth 2WD fitted with the original Ford dump valve

This PAFCLASSIC® Silicone Boost Hose Kit replaces the original boost hoses with reinforced silicone components engineered to cope with the demanding conditions of a turbocharged Cosworth engine while maintaining the factory boost system configuration.

The kit includes 3 silicone boost hoses manufactured from 3-ply silicone reinforced with polyester textile fibres. This advanced construction delivers excellent resistance to high temperatures, pressure fluctuations, and the continuous stresses experienced within the turbocharging system, providing significantly greater durability than conventional rubber hoses.

Designed as a direct replacement, these hoses ensure precise fitment with the original Ford dump valve arrangement. They are an ideal solution for restorations, preventative maintenance, or improving the long-term reliability of a Cosworth engine used on the road or in more performance-focused applications.

Alongside their functional benefits, PAFCLASSIC® silicone hoses provide a cleaner, more refined appearance within the engine bay. Available in a selection of colours and with or without the PAFCLASSIC® Logo, they allow you to personalise your Sierra Cosworth while maintaining premium manufacturing quality.
