Cheap and Easy Engine Air Filter Replacement In A 2017 Audi A4 (B9 Platform)

In this video, you'll see how easy it is to replace the engine air filter! Some cars are even easier and don't require you to unscrew the filter housing. It's usually held in by clips.

The only tools you'll need to replace the air filter are:
1. T-20 Torx bit: https://amzn.to/3j3byQw
2. Engine Air Filter (I bought the K&N Filter, part # E-0646): https://amzn.to/3j7Ujxl
