It can alert you to an impending IMS failure. It doesn't fix anything, but it reportedly can give you a heads up that things are going badly and you might not want to drive the car much further --check it out first, though.

FTFY!
From everything I've read, the IMS guardian basically utilizes the same technology that "chip detectors in aircraft turbine engines. Basically a magnetized plug is inserted into the oil system. The plug is designed to be an open circuit. Ferrous metal in the oil is attracted to the magnet. if the metal particles are large enough or in sufficient quantity, it closes the circuit which cause a warning in the form of a caution light or audible warning or both. A failing IMSB may release ferrous particulate into the oil stream, or it may be confined to the IMS tube. The guardian is inexpensive insurance. However, If IMSB failure is a real concern to an owner, I think the money is better spent on a magnetic drain plug and a Durametric code reader. Checking cam deviation regularly is easy and you have a host of other diagnostic tools at your disposal. Magnetic drain plug should be thought of as a back up check at oil change.
