I can get the filters for about $18 a pop out the door I think it is close to 1/2 of the cost of the replacement filter I got on my truck now. More filtration is always nicer maybe not necessary but can't be bad at all especially when it's 2micron at 98-99% effectiveness better than the nominal rating on the replacement filters.
But anyway still trying to figure out the mounting looks like it's going to be fun finding a spot to put it and still have easy enough access to service.
