Pro Hoses Enlarged Cold Side Boost Hose for Focus ST / RS Mk3

This enlarged cold side pipe made from silicone is an upgrade for our AIRTEC Motorsport big boost pipe kit.

It replaces the cold side aluminium hard pipe and silicone connectors with a single piece, high-quality Pro Hoses silicone pipe. This is easier to fit, features less connections and has an improved internal flow due to less restrictions in comparison to  the aluminium hard pipe. 

Only available in black
