Air Filter: Keep or Replace?
Here's the air filter from my 2009 TL SH-AWD. At 25k miles, and my MID said it's time to change it.
Keep or replace?

Change it. While your at it, you probably need another cabin filter too.

Too dirty. Change it.

If you have to ask, then it needs to be changed.

Thanks everyone for the feedback. I just replaced the old one with a K&N 33-2403 Panel Air Filter that can be washed and re-used. Took less than 5 minutes.
According to the K&N FAQ (link), I'll only need to wash the new filter if the accumulated dirt covers the wire screen of the air filter. Pretty painless.
