Good, rockauto is the shaznats. I get nearly EVERYTHING from them as far as regular maintenance goes. Obviously not fluids/filters but everything else. Save a ton of $$$ too and the site lets you see what parts will ship from what places which is really cool so you can combine all the parts that ship from the "B" location for example and if you know which location is closest to you you can try to order parts from that one to expedite shipping.
They are also one of the only places I've found OEM Motorcraft 96-98 plug wires which are $50 vs $75 for the FRPP ones and work the same AND the Motorcraft ones are black vs the red/blue for the FRPP ones. That is just one example. Also great to order good brands of rotors that don't suck and have runout issues like the local parts store ones. Centric, Wagner, Raybestos etc... Rockauto carries all those brands.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
