Just checked the price at the parts counter, list price on a factory filter is $23.00. I'd probably stick with the factory filter, but I'm sure there's cheaper ones out there. You could also not use the recomended oil and save even more money!

Then you could put on some 17" wheels and be able to save a bunch on tires!

Run the old filter through the solvent tank, and then you could re-use it! Oh wait, just don't change the oil! That would save you the cost of the oil and filter!
Sorry, just really bored at work waiting for 8:00 to get here.
If you would like to order one we have 5 in stock. Call the parts dept M-F 9:00-6:00 at 419-227-0202. Not sure about shipping costs though.
