Product Details

Gates 26299 is part of the Turbocharger Hose (Molded - Standard) line, which focuses on OE-style molded hose geometry for reliable engine connections. For turbocharged Audi A4 and Audi A4 Quattro models, the correct hose shape matters because the cold-side intercooler-to-engine route must maintain a stable seal and proper alignment under boost and heat. This hose is built with a reinforced, multi-layer structure and a silicone cover to handle oil exposure and harsh under-hood conditions while preserving the intended fit. This part cross-references Febi-Bilstein 26299 for the same application.

Common Problems This Hose Can Address

• Cracked or split intercooler hose material
• Boost leaks caused by worn turbocharger hose connections
• Oil-soaked hose surfaces that no longer seal properly
• Heat-related softening or deterioration in the cold-side charge-air path
• Fitment issues from a distorted or collapsed molded hose

Installation Notes and Tips

Verify the vehicle application before installation: Fits 2005-2009 Audi A4, Intercooler to Engine (Cold Side), and Fits 2005-2009 Audi A4 Quattro, Intercooler to Engine (Cold Side). Confirm the hose routing, inside diameter, and centerline length match the original part before removal. Inspect adjoining clamps, pipes, and sealing surfaces for wear or contamination so the replacement hose can seat correctly. Part number 26299 is listed for the cold-side intercooler-to-engine position only.
