Fitment notes
The reservoir was designed as a replacement to 2x original BMW SKUs: 32411097164 and 32416851218. From what I gather, it will fit the E30, E36, E46, E34, E39, E60, X3, X5, Z3, E82, E9X, E84, and E83.
4x color options.
The reservoir is available in 4x anodized finishes: blue, red, black and silver.
Naturally aspirated M engines generate massive heat. They love to spill PS fluid all over their reservoirs when driven at sustained high RPMs.
It may lead to pump failure - it did on my V10, and my E46 M3's reservoir has been leaking forever.
To potentially solve this: capacity matters, design matters most.
In this Series, I document the culprits, available solutions, and my experience with the Performance Power Steering Reservoir.
