Did not work well with my 2010 BMW 528i, and I had to re-installed my old ones again (the Bosh that came with my car, for my car not to shake and ride really rough with the new coils. I will buy the originals again when I get a chance. I give them 4 stars because their great return policy, and because a set of original fuel injectors that I bought from FCP Euro when I order this coils are working Awesome!

Had lots of misfire issues for awhile. Originally had the Genuine BMW (Bosch), replaced several times with the Genuine BMW (Bosch) and problems would come back. Switched to the Delphi and have not had any issues since.

Fast shipping A+

Thes comletely eliminated the stumble on idle, days code condition which was a little embarrassing. 300 miles absolutely rock solid. And as promised they credited through life-time warranty the Bosch set that failed. Let gethis company for over 15 years.

Works great. Recommended especially for the lifetime warranty.

My '06 Z4 3.0SI had developed a stumble at idle and acceleration, my BMW mechanic said the code was number one coil, he suggested I go with Delphi instead of Bosch. They arrived promptly and install was a snap, each of the boxes was factory sealed with hologram sticker. The Delphi Ignition Coils immediately cleared up all issues, no more stumble at all. I'm super pleased with the purchase and recommend this part. Dan

Perfect coils, much better then oem bosch ! Fits well ! No misfires any more !

These are very well built and function flawlessly. The only issue is that when you pull them out, the rubber boot, is so well attached around the spark plug, that it separates from the actual coil. This happened on 3/6 coils when removing. If you are very careful and wiggle them out, that might help, but that is the only issue with these.

Coils fit well. Work great !!

Very high Quality and excellent service
