Cusco's Magnetic Sump Bung is a great addition to any engine, using a powerful magnet, it collects small pieces of metal that may be in the engines oil as it circulates through the pan.
This is useful in two ways, to catch harmful debris in the engine before they cause more damage and also to help visually see if there has been damage.
