K&N Panel Filter - B9 A5/S5/RS5/45 TFSI/3.0D

K&N panel air filters install easily into your factory airbox.

The K&N filter is a permanent, high performance filter that can be cleaned, re-oiled, and used many times over.

These low restriction air filters allow the engine to breath more freely, which means better throttle response and approximately 1-3HP gained throughout the rev range.
