Racing Line’s Haldex Magnetic Plug Set attracts and separates out the minute abrasive and ferrous metal particles in your Haldex’s lubrication system, reducing the sludge that blocks the filter. Protect your AWD system and keep it operating like it should with this simple cost effective upgrade. If you drive an MQB all wheel drive, it will use the Haldex system. It’s a clever coupling system that allows the rear drive to be brought in only as it is needed when front wheels loose traction. The Haldex oil is very specific and promotes friction between the faces of the multi-plate clutch setup. Inevitably, this wear between the plates causes minute particles to slowly build up as a sludge within the oil. This sludge builds up around the pump's oil strainer, which gradually stops the Haldex system from working properly. Many owners have experienced their AWD car slowly becoming FWD as this filter blocks up. Racing Line’s Magnetic Haldex Plug is a two-piece kit of Magnetic Drain and a Non-Magnetic Fill Plug. It attracts and separates out these minute abrasive and ferrous metal particles, stopping them circulating around the Haldex’s lubrication systems and reducing the sludge that blocks the filter. Install couldn’t be simpler – choose our Magnetic Haldex Plug Kit for your next service. Screw in the two new plugs, and you’re protected.
