I have not verified this info, though did get as far as the quick order page just fine.

Go to:
http://www.filter1.com/
Click on ”Online Ordering and Quote System!”
Click on “Online Ordering & Quote System” (again) (or you can go here directly https://order.filter1.com
Click on the “Click Here” button for “If you are already a Filter1 customer”
Enter “moparts” for the Customer Number
Enter “moparts” for the Password (Both are case sensitive so use lower case for both)
Click on “Login”
Click on “To go to the Quick Order Form, CLICK HERE.”
Enter the WIX part number and quantity
