Kaley Brownlee, Mufreesboro, Tennessee
Fits well and the washable nature fits great with our company, All In One Recycling. Best money I have spent on the trucks to date. Would highly recommend! (38-2012S Heavy Duty Air Filter)

This is the second one I purchased. Replacing the first one after three and a half years. Does a great job.
Terry Beebe, Louisiana
I am very pleased and very impressed. I installed this in my semi truck my fuel mileage increased dramatically I have more power and the fuel mileage has increased. The truck also runs a lot smoother . I am saving money by using less fuel I also am saving money in the long run by not having as much wear and tear on my engine from straining trying to breathe. Plus the cost of not replacing the air filter every few months.
