Bosch Automotive Ignition Rotor 04271/1234332422 Review

Installed this ignition rotor on my car and it has been running smoothly ever since! I noticed an immediate improvement in performance and fuel efficiency. The quality of this product speaks for itself, as it is made by a well-known brand in the automotive industry. The only downside is that it is slightly more expensive than other options on the market, but the reliability and peace of mind it provides is well worth the investment. Highly recommend!

I ordered Bosch specifically to make sure it was the OEM equivalent. After 3 months my 8 cylinder MB was only running on 4 cylinders because the rotor integrity was broken. Although the part is guaranteed for one year, I could not find a way to return this defective part to Revain as it did not meet Revain's standard 30 day deadline.

This quality is no worse than the original precision part. In fact, the part you buy from your MB dealer in this case is the same part from BOSCH but almost double the price. As the description says, this is an updated version of the rotor. If your car is older and hasn't had rotors changed in the past, you will most likely need to replace the brackets as well. Only fits 1191580640 brackets, not 1191580440 brackets. Make sure you have 640 brackets or order them as well.
