Gates 26257 Turbocharger Intercooler Hose - Pipe to Intercooler (Hot Side)

Gates OE-Exact Turbocharger Hose

The Gates 26257 turbocharger hose is an OE-exact molded intercooler hose for the hot side connection between the pipe and intercooler. It is built for Volkswagen and Audi turbocharged applications that need a precise molded fit, stable reinforcement, and resistance to heat and oil exposure.

Gates Turbocharger Hose (Molded - Standard) line focuses on direct-replacement hose geometry and durable construction for factory-style routing. For Audi A3, Audi TT, Volkswagen GTI, and Volkswagen Jetta applications, this hose supports the original under-hood layout without changing the connection path.

• OE Exact comparison rating for factory-style fit and routing
• Molded hot-side intercooler hose for turbocharger plumbing
• Multi-layer construction for reinforcement, durability, and strength
• Silicone outer cover resists oil, contaminants, and high under-hood temperatures
• Inside diameter: 2 in. / 51 mm
• Centerline length: 16.375 in. / 416 mm

Detailed Product Overview

Gates part number 26257 is engineered as a molded turbocharger hose for the pipe-to-intercooler hot-side connection. The OE-exact shape helps maintain proper alignment in turbocharged Volkswagen and Audi platforms, including the 2006-2013 Audi A3, 2009-2014 Volkswagen GTI, and 2008-2010 Volkswagen Jetta. The reinforced construction and silicone cover are selected to handle heat cycling, oil mist, and other engine-bay contaminants common in boosted applications. This part cross-references 1K0145832AS and 1K0145832J for the same application.

Common Problems This Hose Can Address

• Cracked or split intercooler hose material
• Boost leaks at the hot-side pipe-to-intercooler connection
• Softening or deterioration from heat and oil exposure
• Collapsed or distorted hose shape under engine load
• Loss of factory routing accuracy after hose failure

Installation Notes and Tips

Verify the inside diameter and centerline length against the original hose before installation. Confirm the vehicle’s engine and turbocharger plumbing layout, especially on Audi A3, Audi TT, Volkswagen Eos, and Volkswagen Jetta models, since fitment is specific to the hot-side pipe-to-intercooler position. Inspect adjoining clamps, pipes, and sealing surfaces for wear or damage before reassembly.

Quality Assurance

This Gates hose is built to OE-exact standards for direct-replacement service in factory turbocharger systems. Gates uses reinforced construction and a high-quality silicone cover to support durability in demanding under-hood conditions.
