Filter heads can be mounted in any attitude, but we suggest when choosing an oil filter that is to be fitted in other than an upright, filter below, position, it should have an anti-drain valve. No provision is made in our heads for filter relief valves, these are available built-in on some filter elements, they should be avoided if regular oil changing and gentle warm ups can be relied upon.
