Pro Hoses Enlarged Cold Side Boost Hose for Focus MK3 ST / RS

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

It replaces the cold side aluminum 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 aluminum hard pipe. 

Please note: Will only fit with our AIRTEC Motorsport big boost pipe kit: AIRTEC Motorsport 2.5-inch Big Boost Pipe Kit for Mk3 Focus ST250

Only available in black
