Once it is used, the burnt surface will be removed by the pad, and changes back to the colour of normal cast iron. Please be aware that the effect of the heat treatment of the disc will not disappear even if the surface colour changes. _x000D_ our processing of the rotor is, we have shipped in the above package.

Quick solution to replace that OEM Plastic Mount in your BMW E90
Effective Upgrade: After installation, I have experienced no leaks, which is a significant improvement for my vehicle.
Quality Material: The aluminum construction feels durable and sturdy, offering a long-lasting solution compared to the original fitting.
Cons:
The installation process was a bit tricky. The holes didn't line up perfectly, making it a challenge to fit. While there was no need for drilling, finding the right angle to fit it required some patience and effort. Wider holes could have made the installation easier. I rate it 4 stars because of that.
Despite the challenging installation, the Aluminum Water Hose Fitting Upgrade is a worthwhile investment for anyone experiencing leaks. The improved performance and durability make it a recommended upgrade for BMW E90 owners.
