This product is a must-have when swapping any V8 into E46 and Z4. Left side runners will collide with the stock intermediate steering shaft due to its diameter.
This one has a smaller diameter. It’s all to leave as much room as possible for the left header. Such a solution makes the fabrication of exhaust manifolds much easier.
It’s a 100% bolt-on solution – you simply install it in the place of the stock shaft. For maximum safety, the shaft is collapsible. In case of a front crash, the shaft will fold. It will save your precious cylinder head from being hit by the steering wheel.
