Turbo Inlet Hose, High Flow Silicone, C4 Audi S4/S6, Aan


We're pleased to offer our High-Flow Silicone Turbo Inlet Hose for the Audi UrS4 and UrS6!

Factory rubber turbo inlet boots get the job done decently on a stock application, but have many problems once boost is turned up and performance increased. 

Due to the lack of reinforcement, its common to see the stock hose collapse under extreme vacuum created by the turbo's suction - and also a common area to see cracks and leaks which throw off MAF readings. 

Since our hose is not corrugated, it flows much smoother and flows more air than the OEM hose, and its a direct fit to boot. Constructed from high quality, automotive grade silicone using 4-layers of reinforced nylon - the finest quality.
