I'll probably catch HECK about this from some of the wingers, but here goes..... I paid close to $19,000 (including accessories) for my '02 1800 and I wouldn't knowingly do anything to harm it....... But Honda is soooooooo excessive in price on everything they sell. One day I passed by the Auto Zone in my hometown and thought, what the heck, I'm gonna see if they carry any motorcycle filters...... The assistant mgr., who's been there the whole 10 years that the store has been open said, "yeah, we have 1800 wing filters. The price was $3.99....... I opened the box and looked at it and remarked, "This looks exactly like the Honda filter, color and all. He said, "That's because it's made by the same company that makes the wing filters for Honda, it's the same one"..... The mgr. said that he could show me his paperwork and I could try to find out from Honda who makes there's, if they'd tell me..... (which they probably wouldn't)..... I've been using it for several oil changes and as far as I know, it's fine..... $12, even $6, is too much for a "Honda" filter.
Some guys badmouth FRAM filters in articles..... I've been using them for 35 years. My '68 Firebird 400, 335HP, thought FRAM was great. Just my opinion..... Stobby
