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.
High-Quality 4-Ply Reinforced Silicone Construction
Just received and installed the hose yesterday. All of the inputs were where they should be, although I ended up re-using a couple of clamps as the larger included ones were a little overly large. Nice product and cheaper than stock, an added plus. The only reason for fewer than five stars is that some of the included clamps were on the cheap end with cadmium plate hardware versus stainless.
I received a red inlet as ordered, got it within a day with overnight.. instal was fairly easy, slight fab work with my air filter though.. performs excellent, a more refined turbo sound, and I'm peaking at 20psi as I'm supposed to! Old inlet had massive cracks causing boost creep and maf sensor readings being thrown off. Couldn't be happier with the power I was loosing and now is back. Thanks 034
