5 Stars
Good filter housing and price
The filter housing and brackets are great. Great construction and was easy to install. I had to switch the bracket for in/out flow and that was easy to do. My only recommendation would be to offer this single housing in a 3/4" inlet and outlet ports. The 1" just resulted in more fittings.
