I just purchased a 91 Accord. I'd like to buy quality OEM filters. Previously, the Japanese vehicles I have owned were Mazda and their OEM filters were made by Toyo Roki or Tennex. Both were high in quality. I've read some Honda OEM filters are made by Fram. I avoid Fram like the plague. What is the part number for a Filtech or Toyo Roki filter and where can I find them discounted for mail order THANKS!!!!!
