Mishimoto Turbo Silicone Hose Kit Blue 97-02 Audi S4

Replace and upgrade turbo inlet and charge piping connections with the Mishimoto Turbo Silicone Hose Kit Blue 97-02 Audi S4 to provide efficient heat reduction and increased pressure tolerance.

The Mishimoto Audi S4 Silicone Turbo Hose Kits are manufactured by combining high-grade silicone and heat-resistant embedded fibers to provide efficient heat reduction and increased pressure tolerance.

• High-grade silicone construction — Provides a durable, flexible sealing surface that resists deterioration from heat exposure and repeated boost cycles.
• Heat-resistant embedded fibers — Reduce heat transfer into the intake and charge system, preserving component temperatures and material integrity.
• Direct OEM fit — Designed and engineered for a direct OEM fit to simplify installation and maintain factory routing and connections.
• Mishimoto engineering — Built to Mishimoto standards for consistent material quality and manufacturing control.

Application-focused design emphasizes reliability and repeatable performance under thermal and pressure loads encountered in turbocharged operation. The kit's materials and construction target improved resistance to heat soak and higher boost pressures compared with standard rubber hoses.

Installation notes: the kit is engineered for direct OEM fitment to the 1997–2002 Audi S4 charging system to match factory attachment points and hose routing.
