My Ride: '08 X3 6MT/135i 6MT
Either DIY the seals yourself, or pick up a refurbed unit from Dr. Vanos. When we pulled my seals out, they were brittle, but not broken. Initially, I didn't notice a HP difference, but over a few weeks, the car seemed to feel stronger. I don't have any dyno proof of it though.
