Hi Rick
Had to go out to the shop anyway so brought in the filter interchange catalogs. Started with the oldest 1990 looking at Purolator N-15 not listed but they had a Purolator N-1500 that cross referenced over to the what Rob found "NAPA NGF 1080" if you want to check the dimensions and information to compare of the with what you have try this link
http://www.napaonline.com/Catalog/Ca...080_0338264248 on that page you can click
Buyers Guide and it will give you a cross to all the vehicles and equipment that uses that filter. I've found this information useful in tracking down sources. Quick look says it was used in a lot of stuff.
Also checked the 2007 NAPA filter catalog and it is showing the same N-1500 with a NAPA number of 1080.
I know the NAPA numbers don't help much but their numbers are the same as Wix with the first number dropped from the Wix 5 is oil filter designation. Just called my local NAPA and they confirm that Wix 51080 and NAPA 1080 are still in the system.
Cost in US dollars is list $25.32 with normal shop discount down to $14.49
Hope this helps.
Cheers Phil
