DLC stainless steel piston suitable for S54 oil pump Z4 M E46 M3 incl. CSL BMW

Replacement control piston for the oil pump of the S54 engines. The new control piston features a DLC coating for excellent durability.

The ideal replacement for an engine overhaul or connecting rod bearing replacement. We also recommend replacing the O-ring on the control piston. You can find this here in our shop.

This piston replaces the original aluminum piston with a notch (please check before installation). If your pump itself is damaged, you can find a new one here.

Features:
- DLC coated (Diamond-Like Carbon) for an extremely low coefficient of friction and high hardness.
- Made in Germany!

A NOTICE:
If we do not explicitly mention a parts certificate or a general operating permit (ABE) in the product text, it is a motorsport article that is not approved under the Road Traffic Regulations (StVO) and therefore the operating permit will expire if no entry is made in accordance with Section 21 StVZO!

Please note that vehicle spare parts should only be installed by a qualified specialist workshop to ensure their proper function and the roadworthiness of the vehicle.
