Purchased as a replacement filter, fit perfectly and I realized I should have replaced the old filter sooner
I have used these filters in the past, but they were difficult to find. Now I have a reliable source.
Since changing to these filters I do notice less dust near the exhaust muffler.
The product is less impressive than the fact that MD had what we wanted. I looked at other sites with less success. They had it and shipped it within a reasonable amount of time.
Works great. Good, quick service.
