Purchase & Delivery:
The purchasing and delivery process was smooth, and I received the coils on time in proper Bosch packaging. At first glance, they looked original and carried the Bosch stamp.
Quality & Build:
However, I need to be honest, the build quality does not feel the same as the original Bosch coils that came with my BMW Z4. These coils were stamped Made in Slovenia (not Germany), and just from handling them, the texture and material seemed lower quality.
During installation, one coil actually came apart internally (plastic and rubber separated), which I had never seen before. Also, the clips at the top that secure the electrical connection feel flimsy, and one partially broke while installing. I was still able to install it, but that was disappointing.
Performance:
To be fair, all six coils are working. My car’s misfire on cylinder 5 is gone, and the engine is running smoothly without shaking or vibration. So, performance-wise, the product does its job. However, I don t know how long they will last. The original coils were 19 years old.
Overall:
While the coils are functioning, the build quality raises concerns about durability and whether these are truly the same Bosch standard as before. They may be genuine, but they don’t feel as solid as the German-made originals. Buyers should be aware of the potential quality difference before purchasing.
