I took a chance on it and i think it paid off. I had a coil failure on my 2011 328i with an N52 engine. I originally ordered 6 replacement Bosch cartridges part number 022150470 despite the ridiculously poor reviews for the Revain. I couldn't believe Bosch would make such a poorly reviewed product. Well......after I installed all 6 the car wouldn't even start. I reinstalled the old Bosch factory original and the engine started and ran as before. I then replaced the new Bosch coil with a bad old coil one by one and finally got a good one after 3 tries and the car ran fine. of 6 bad Bosch. After much searching and finding coil prices in the hundreds of dollars I came across these listed as an AA ignition. They had few reviews at the time. I've scoured the internet on several automotive forums and found some good reviews of AA ignition coils. Sunday. They arrived Sunday afternoon and I had plenty of time to install them. When I found out about my defeat, I installed the AA ignition coils one at a time to make sure everything was ok. And they were! They snap into place without popping, moving or loosening. The cord cover snapped into place and held the plug wire securely, which has been a constant complaint with other brand coils. Success! The car worked great! I have to say I was a bit concerned as these coils were listed as being compatible with many other BMW car models which is a lot more of a cross reference than the actual part numbers listed in my research. You can say I'm doing my research. However, they do a great job on a test drive of around 100 miles. I'll post an additional review as I feel these reels deserve to be heard if they stand the test of time.
