How much does an oil filter cost for an Audi A4?

Buy a Wick brand filter from an auto parts store that carriers them, they are as good as OEM Audi filters and cost about $12. Don't use a Fram or other lower cost brand. Store will match to your vehicle. I know O'Riley's carry Wick filters. Buy a Wick brand filter from an auto parts store that carriers them, they are as good as OEM Audi filters and cost about $12.
