The K&N E-1983 is a round, drop-in replacement air filter built on K&N's oiled cotton gauze media. The manufacturer describes its layered construction as a trap for harmful contaminants, and it says the filter is reusable and built to last the life of the vehicle. Over time that means washing and re-oiling one element instead of buying a disposable paper filter at every service, which is the practical case for paying more than a stock filter costs. The manufacturer also states it is designed to increase horsepower and acceleration, but no gain figure is listed here, and owners on user forums report mixed results, with some noticing crisper throttle response and others seeing no clear difference.
Fitment is the first thing to verify. The manufacturer's listing places this filter in the Audi A7 V6 3.0L range for 2010 through 2017, and published A6 and A7 year ranges vary, so confirm against your VIN before ordering. Installation is a drop-in job that requires no airbox modifications. Owners on user forums describe removing the engine shield, loosening the bellows clamps, and rotating the airbox outlet to reach the element, and they report that debris often collects inside the box, so vacuuming it out during the swap is worthwhile. Search terms that fit this part include K&N E-1983 Audi A6 quattro drop-in filter, C7 3.0T intake filter upgrade, and reusable cotton gauze air filter for Audi 3.0 TFSI.
The manufacturer lists this filter for the Audi A7 V6 3.0L from 2010 to 2017. The A6 and 2012-2013 A7 years in this product's title do not match that listing exactly, and owners on user forums have fitted it to C7 A6 models. Confirm fitment with the manufacturer's fitment tool using your VIN before ordering.
The manufacturer states the element needs cleaning about every 75,000 miles under normal highway driving conditions. Stop-and-go, dusty, or off-road use calls for more frequent inspection than that figure assumes.
The manufacturer lists a re-oiling amount of 3.83 oz (113 ml) for this filter.
This is a beginner-friendly swap. Owners on user forums report it takes roughly five minutes once the airbox is open, and the main tool is a screwdriver for the intake hose clamp. Remove the engine shield for access, loosen the clamps on the bellows, pry the bellows off the airbox outlet, rotate the outlet to release the old element, and seat the new filter on the small tube at the bottom of the box. Owners warn against over-oiling, because excess oil can migrate onto the mass airflow sensor, so apply only the amount the manufacturer specifies when re-oiling.
