If you are unsure about the IMS Bearing in your Porsche engine it would be a good choice to have it replaced
Prevent future catastrophic engine failure permanently with the only true Eternal Fix for the notorious Porsche intermediate shaft bearing. Unlike the other failure-prone ball bearing products that the original IMS and other upgrades on the market use. We use a patented cylindrical bearing with thrust control that can be pressed directly into the back of the engine without disassembly. The cylindrical bearings have over 12 times the load capacity of other ball bearing solutions making this IMS bearing the clear choice. Backed by a full 5-year warranty
