Take the old filter with you.  They can probably match it.  Does the previous owner know the part number?

If the Auto Parts Store asks what it is off of; tell them it is a custom made, three wheel, off road vehicle.  I doubted the filtering efficiency when I could see daylight thru the K&N.  We used to call them rock strainers on Hot Rods.  I would like to compare a paper media filter with the K&N I fitted to the IO-550N in our Legacy.
