Pick an answer

1. It only affects engine sound, not the air quality feeding the compressor or the tanks downstream
2. A clogged intake can make the compressor work harder and draw in dirt that contaminates the air supply over time
3. A dirty intake only matters for fuel efficiency, never for air quality
4. The intake has no connection to the air brake system at all
