Replacement reinforced silicone breather hoses for the VAG 150/180 BHP 1.8T engines. A known problem is the failure of the OEM rubber hoses after prolonged exposure to engine oil and fuel vapours. This leads to poor running and check engine lights. These uprated silicone hoses have an oil resilient lining to ensure longevity. Available in red, blue, or black. These hoses are suitable for engines coded: AUM,AUQ,ARX,ARY,BVR and BVP. The OEM hoses which are replaced are 06A 103 221 BH/AH and 06A 103 221 AF/BK. The Forge silicone hoses in this kit have been designed to include an expensive inner liner of modified silicone known as Fluorosilicone. This means the hoses are suitable to be used with either modern long-life coolants, Organic Acid Technology coolants (O.A.T.) or air containing oil mist. The construction of the hoses has been engineered to exceed that of the OEM fitments, and will enhance any engine bay both technically and aesthetically The use of a Fluorosilicone liner ensures that Forge silicone hoses are the clear market leader.
