I've never worked on my car before.
But after googling some mechanical issues for 10 minutes I'm confident I can do most of it myself.
Replacing the Air filter is a piece of cake! Definitely something you can do in less than 20 minutes and is pretty cheap.
Step 1: Open the hood!
Step 2: Locate air filter and air filter gauge. When I first did this the gauge was at 100% red, but I flipped it down to 0% without taking a picture first. My bad.
Step 3: Remove heat shield. Three bolts. Easy.
Step 4: Remove hose clamp and two plugs. 1 screw. Easier.
Step 5: Unclip Air filter compartment lid and remove air filter. You can do this with just your hands.
Step 6: Clean out air filter compartment and put new air filter in. Napkins recommended.
Step 7: Close that baby up. Boom.
This was a fun thing to replace. It was easy to do on my own and gave me a bit of confidence in my own abilities to work on my car. A lot of what holds me back from working on my van is my own ignorance of how it operates, after doing this I was able to have a better understanding of my vans inner workings.
