Ferrari Mailing List: Cost of Air Filters

[Larry Bard (larrybard]

I've been offered some OEM air filters by a fellow 512TR owner who doesn't need them anymore because he's switching to K&N filters.  We both clearly want to be fair as far as price.  But I'm not sure I have a useful reference point for a new filter; Rutlands is offering some on eBay for about $75 -- or "Make Offer"

and I've seen others for about $27, but it's not clear they're OEM, so I'm assuming at that price they're not. http://www.eurospares.co.uk/searchResult.asp?S=148718 .

Any useful suggestions for a fair price?  I'd be getting 4 OEM filters from this individual -- two new/unused, and another two with less than 5K miles of usage (and therefore, it seems to me, of far less, or negligible, value).

Thanks,
Larry
