About 15 minutes. The tool that the filters provides helps a lot. You’ll also need a small flathead screwdriver and a T20 (provided in kit).
Trickiest thing was getting the speaker under the dash to un-clip. I couldn’t get the clip to pop loose. After a few minutes I got it free. The side panel just pops off with help of the provided tool. remove 1 screw, pull the old ones, replace, and put it back together.
YouTube vid I watched before I did it suggested kicking your air on once you replace the filters and screw to make sure they’re seated in there properly. Shouldn’t hear any whistling.
