SMG Pump Tank Upgrade, MLR - E46 M3 SMG

This SMG pump end tank is made from aluminum, features cooling fins, and a drain plug for additional service capability on the SMG pump used in E46 M3. The original pump uses a plastic oil tank integrated with the pump. Plastic has a poor track record when exposed to heat and chemicals for a long time. While we don't know of SMG problems directly related to the plastic tank, upgrading and improving SMG servicing is a good thing in our mind.

Features -
+ aluminum tank bolts directly to OEM pump
+ cooling fins allow some heat to radiate from the system
+ new drain plug to flush the system without complete removal (drains toward motor mount)
+ all hardware and gaskets to install are included
