034Motorsport is proud to offer our Silicone Throttle Body Inlet Hose for the B8 Audi S5 4.2L FSI V8!

This hose is designed to replace the restrictive corrugated plastic unit, and features a larger internal area and smooth inside for higher flow and life long durability.

This durable, high quality silicone hose was modeled directly off of the factory part to ensure perfect fit and finish, and extensively tested at 034Motorsport and by our development partner, JH Motorsports. In addition to cloth reinforcement, this hose features stainless steel wire reinforcement to prevent collapse under vacuum.
