A set of Silicone Boost hoses for the Audi A4 B8 2 litre turbo. Being modeled directly from the OEM hoses, these new precision engineered parts are an easy and direct replacement for the factory items, yet offer significantly greater ability to withstand much higher temperatures and pressures. Ideal on a standard car, but absolutely essential on a tuned, track or modified example! Allied to this, their superior woven fabric reinforcement and fluorosilicone internal lining, means that they will last an awful lot longer than the factory ever intended, too. Three dynamic colors are available. Choose black for understated elegance, or blue or red for trackside or show arena presence.
