Air Filter part number?

[William Schnieber]

I'm sure it's somewhere in here but I can't find it. Does anyone know the part number for our air filters and a supplier? I'm also looking for a drive belt. (400 ISL ENG#46366601).

NAPA has the belts.

Yep...just got the Napa part number...it's K080685.

Thanks wolfe10.
I couldn't find the Fleetguard but I did find the Wix. Do you know if the Wix is good...because that's what I just ordered. I would imagine the Fleetguard is probably superior, just curious.
And thanks for all the parts numbers and info.

Yes, nothing wrong with Wix filters. They make a lot of high-end filters for others as well. It is my understanding that NAPA Gold filters are also made by Wix.
