6637 air filter

[yzmatt]

Does anybody know if caterpillar alternate filter better then the napa light dust 6637 filter. I'd rather spend a few bucks more for the security and peace of mind. A ford diesel mechanic told me here the dust is to fine for most dry filters and said that ford's ais filter is the only one he would use.

Ais is probably the best filtering but 6637 does fine. Donaldson b085011 is the same as a 6637

Thanks. How long you have had yours

Hell probably 5 years 50k miles

I trust my $100k generator to Donaldson so I wouldn't hesitate to put one on my truck!

Is it windy and dusty where you guys are at? High desert where I'm located.

Get the AFE big boost I started out with a 6637 but switched to the afe it flows 400 cfm more than the 6637 its washable and the same size as the 6637 but has a cone in the end for more filter area. I know I sound like a sales man but its a good filter

The mechanic that got to wondering about filters said explicitly to stay away from the reusable filters. I was wanting to order afe stage 2 and he said to only issue with fords is the box. The air here is so silty and filled with a fine layer of dust that they are no bueno here. Maybe Seattle. He recommends the Ford AIS. But since talking to him I have to do injector cups and injectors. So I'm just trying to find a less expensive way to get air in and out for now that will help me with stage 1 injectors and a mild setting chip to run those injectors. Hoping that these conversion will be the ticket. Thats why I started the post on wanting a 6637 filter that will stop super fine crap in the air.
