I highly recommend that everyone join an online forum for their car - make and model. You learn SO much on there and many things are posted with step by step photos for DIY.
You will also find links to lower cost replacement items -- we can get the 2008 Prius cabin air filter for half price at one dealership in Georgia, and they offer free shipping! The local dealership charges $75 to replace your cabin air filter (filter included), when I can buy it for $10 and do it myself in less than 5 minutes.
And there are many tips on increasing gas mileage, explanations of what tires to get, after market improvements to your vehicle, just terrific stuff. Also a great place to go, to post if you are having a problem, they can narrow it down for you.
Glad you found and changed your filter, Candace!
