Gates 26291 Turbocharger Intercooler Hose - Intercooler to Engine (Cold Side)

OE-Exact Turbocharger Hose for Cold-Side Routing

The Gates 26291 turbocharger hose is an OE-exact molded intercooler hose built for the cold-side connection between the intercooler and engine. It uses multi-layer construction for added reinforcement and a silicone cover that resists oil, environmental contaminants, and high under-hood temperatures.

Compatible with select Audi TT, Audi TT Quattro, Volkswagen Golf, and Volkswagen Jetta applications, this molded hose supports a precise factory-style fit where the turbocharger charge-air path needs reliable sealing and stable routing.

Common Issues This Hose Can Address

• Cracked or split turbocharger hose material
• Oil-soaked hose surfaces that weaken sealing performance
• Heat-related hose deterioration in the charge-air path
• Loss of boost pressure from a damaged cold-side hose
• Fitment problems caused by a distorted or collapsed molded hose

Installation Notes and Tips

Verify the inside diameter and centerline length against the original hose before installation. Inspect adjoining intercooler and engine connections for wear, residue, or damage that could affect sealing. Confirm the hose routing matches the cold-side position listed for your vehicle before final assembly.
