Performance Power Steering Reservoir

Swipe right for info.

No, more, leaks.

The cap is designed to eliminate leaks when the power steering system is under high load and temperatures.

Improved thermal capacity.

The reservoir is enlarged and allows an extra fill of 180ml.

ORB AN fittings.

This is verbiage to say the fittings can withstand extreme pressure. They are pre-fitted to the reservoir.

Machined in the USA.

The reservoirs are machined from 6061-T6 aluminum in the USA.
Build Journal: special series
They all leak.

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.
