Магнит за маслен филтър.Събира металните частици , за да попречи на попадането им в двигателя. An ingenious idea that is also wonderfully simple: ■A flexible soft rubber cap is securely attached to the oil filter by a powerful integrated magnet, which collects all the tiny metal particles from the oil. This means the oil filter can operate longer before becoming clogged, as even the tiniest metal particles are filtered directly out of the main oil flow. This is a perfect complement to a magnetic oil drain plug (but not a substitute for it). ■Very easy to install: simply attach the "Filter-Plus" to the outside of the oil filter, and the magnet will hold it in place. ■Not suitable for BMW K models ■Filter not included
