If you’ve upgraded the intake system on your C7 RS6/RS7, you’ve likely dealt with the crumbling, cracking plastic accordion hoses that Audi calls couplers. Over time, usually following removal/installation, these plastic couplers can fail, allowing dirt and debris to be ingested into your turbochargers.
Upgrade to a set of GAS silicone inlet hoses and forget all of your intake worries. Not only will these couplers outlast your intake system, but they will continue to look good while doing so.
These couplers are a direct fit replacement for the RS6/RS7 4.0T, and will also fit if you’ve purchased upgraded turbo inlets for your S6/RS6/S7/RS7 and would like to retain an RS or aftermarket airbox.
If you have an S6/S7 and are looking for direct fit replacements, you’ll find them here.
