Product review (4 stars): Fit, Form and Function
These filters looked a bit different on the base.  First thing I did was check that they lined up with the old one prior to installing it into position.  There is a rubber plug or flow restrictor which I left in.  The products fits up just fine no looseness or sloppiness in its fit.  Water flow through the product is similar to a new OEM.  Max. Pressure indicated on the side of the package is 120lbs which is the same specification as the OEM also.
