I have one. Installed it last year and I average 18,000 to 20,000 miles a year so that works out to a payback in two years for me. The best part is how well it traps stuff and I can see if anything is going bad between oil changes. I consider this one of my better purchases.

I have one yes they are a little pricey but it works well and you don't have to go buy a filter just to change your oil. There are other benefits also there may be a slight bit of cooling with the finned aluminum heat sink body. It is compare to having a cleanable air filter gas filters and the like. You also get another magnet to work for you! It has a pressure by pass also.

The one thing I don't see on any of these mesh filters is an anti drain back in the filter. So do you essentually have a dry start everytime you start up after sitting awhile? I could see not needing one if the filter was hanging down but not sideways like ours. Any ideas on this, i think the stock filter has the anti drain back valve. Might not be a big deal, Just wonder'in.

11) Why don't you have an Anti Drain back Valve?
Many filters have a rubber flap over the intake holes that is an attempt to keep oil in the filter and minimize the time it takes to fill the filter when you start the engine (they call it an anti-drain back valve). A test you can perform to see how well this "valve" works is to fill a filter with oil, plug the large center spin on hole with a bolt, lay it on it's side and then see how long it takes for the oil to drain past the rubber flap. We have found (and have read other published tests) that the filter eventually ends up with the same amount of oil in it as if it didn't have the flap, it just takes longer to drain out. If the flap worked as planned it would be beneficial to have the extra oil in the filter at startup. On the other hand, that flap covering the intake holes is one more restriction the oil has to get by to get through the filter and back to the motor....

So a couple of concerns I have are the sealing gasket does it wear out and the removal tool is it good and will it take off tight filters and last etc.My filter always seems a bit tight(Twin Cam) and I install it hand tight only. The math is 8 x $20 for HD filters so in 30-40 k it will pay for itself depending how often you change oil I guess??
