Can anyone recommend an oil filter for my 2003 WR450f besides the $12.00 OE Yamaha ones. I am already aware of the stainless steel ones for $70.00 and am not interested in those right now. I have heard of people using Fram Oil filters that you can buy at Walmart. If you use other brands of oil filters, such as Fram, do you remember the part #? Thanks for any help you have to offer.
