A used genuine OEM Audi turbo intercooler hose (part 8L9145790A, also replaces 8L9145972B) is a left-side hose originally fitted to the 1.8L turbocharged four-cylinder engine. When it cracks or fatigues, boost leaks develop, resulting in power loss and a noticeable hissing sound under acceleration. This is a direct replacement for the original equipment hose.
