We buy all our filters from Filter1....Much cheaper than any other supllier we have used over the years and we buy thousands of dollars worth of filters. Big filters for big engines are not cheap! Especially air filters...

We get them UPS'ed every day.....

Napa prices are way higher...

and yes Napa filters are made by wix....

Same part number minus the prefix...

Wix adds a prefix
5 is oil
4 is air
3 is fuel

So drop the prefix and thats the Napa number....

R suffix is racing filters
We buy the 51061R's......full length filter
I think the 51069R is the shorter filter.....

51060 and 51061 are similar....One has anti drain back valve that is easy to see right thru the holes at the top.......for filters mounted horizonatlly....51060 has it if I recall right...Not needed for a std filter mounted on the block vertically....
