service our trucks every 200 hours. Our air
filters weigh 7lb clean and dry.
After 200 hours our air filters would weigh
17-26lb. With pre-filters on the same
truck we weighed the filters after 200
hours and only gained 4 oz. I would
recommend these. Cody J. Bartlett, NE
Your product works great. Have had them on since day one of the new semi and 36k miles later the filters still look like new. Chris H.
I was having to blow out the air filter daily before sleeve went on. Now I haven't blown the filter out in nearly a week. I can't believe how much stuff the sleeve is stopping from entering the filter. Thanks, Matt - John Deere 9510R
