Detailed Description
This intercooler hose is engineered to match the original hose’s fit and function on select Volkswagen and Audi vehicles. The molded shape helps maintain the intended routing between the intercooler and engine, while the OE-grade design supports reliable charge-air transfer in the turbo system. Part number 667-643 is a practical replacement when the factory hose shows signs of wear, cracking, or pressure loss. This part cross-references 1K0145770AH and 1K0145770N for the same application.
Compatible With 2008-2013 Audi A3, Intercooler To Engine (Cold Side - Left); 2009-2013 Audi A3 Quattro, Intercooler To Engine (Cold Side - Left); 2009-2017 Volkswagen CC, Intercooler To Engine (Cold Side - Left); 2011-2016 Volkswagen Eos, Intercooler To Engine (Cold Side - Left); 2011-2014 Volkswagen GTI, Intercooler To Engine (Cold Side - Left); 2012-2013 Volkswagen Beetle, Intercooler To Engine (Cold Side - Left); 2012-2013 Volkswagen Jetta, Intercooler To Engine (Cold Side - Left); 2013 Volkswagen Golf, Intercooler To Engine (Cold Side - Left); 2008-2010 Volkswagen Jetta, Intercooler To Engine (Cold Side - Left); 2009-2010 Volkswagen Passat, Intercooler To Engine (Cold Side - Left); 2009-2012 Volkswagen Passat CC, Intercooler To Engine (Cold Side - Left); 2009-2017 Volkswagen Tiguan, Intercooler To Engine (Cold Side - Left); 2017-2018 Volkswagen Tiguan Limited, Intercooler To Engine (Cold Side - Left).
What It Helps Address
- Boost leaks caused by a cracked or split intercooler hose
- Loss of charge-air pressure in the turbocharger system
- Damaged factory hose connections at the cold-side left position
- Airflow routing issues from a worn molded hose assembly
- Replacement needs for aging OE-style plastic charge-air plumbing
Installation Notes and Tips
Verify the vehicle’s year, make, model, and cold-side left position before installation. Inspect the mating ends and retaining-ring areas for wear or debris, and confirm the hose routing matches the original layout. Because this is a molded assembly, correct alignment during installation is important for a secure seal and proper fit.
Quality Assurance
