K&N 57s-4000 Airbox cover

1525 2

What?: K&N Airbox lid for Mk3 Focus
Where?: Portland, OR
How much?: $40 shipped
Who?: Me!

Hey, I have an extra K&N airbox cover (no filter included) for the 2012-2014 Mk3 Focus. If anyone is interested, $40 shipped. This is the raised airbox lid/cover that is included in the $160 "57s" kit from K&N.

Here is the link for the intake kit from K&N.

This lid will work with any stock or aftermarket filter designed for the Mk3 Focus.

The second picture shows the difference between the stock airbox lid and the K&N raised lid.

Let me know if there are questions.
