I'm at 18K miles / 4 years. I'm thinking this:

- Brake bleed
- Oil and filter change
- Cabin air filter change
- New windshield wipers

Thoughts on spark plugs? Engine air filters? Not sure that's appropriate for 20K miles but I would love some input given the 4 year part.

 

How are your tires? Check tread depth at the inner edges. Probably too early for a new belt, but that's something you want to change based on time, not mileage.

 

Yep, air filters and plugs should be changed at the 4 year mark. There are a lot of DIYs on how to do plugs and filter. For the filter, rear bumper has to come off, but from what I have seen and heard, it is easy.

 

Yes the bumper needs to come off and it is pretty easy. I just did my own. Took about two hours and most of that time was just taking the bumper off for the first time. The taillight so also have to be removed. Trust me if you have common sense it won't be difficult. Also, the other filters in the car are also easy to change.

 

I just did mine (including oil change) and it was easy. I'm debating on doing the plugs as I only have 20K miles and it runs perfectly. Here's a good checklist:

The oil filter calls for a special grease which I didn't use, but think I will next time.

Ok, so I'll add the engine air filters and spark plugs to my work day. I have all the parts and have read over the DIYs many times.

Tires are fine! I switch summer/winter so both have minimal wear so far.
