Ignition coil Bosch or HUCO
I'm running Bosch and have been for 45k miles with no issues, even tuned running extra boost which demands more of the ignition coils.
I have Bosch in my 2015 currently with no issues for 30k miles so far
I’ve ran Bosche in all my M3’s with great success.
I’ve used Bosch without issue as well.
I've a 09 E89 3.0 and went with the Bosch coils about 2 years & 20k miles ago and haven't had any problems yet
I have a Y2014 2.5L JSW. I went to the BOSCH (a lot cheaper) route and 10K miles later, no problems.
I bought a new Bosch coil from TT because the original in my '88 Scirocco 16V didn't have the exact readings the Bentley said it should have. The new coil didn't have the correct readings either according to the Bentley and it didn't make my Scirocco run better.
Went back to old Bosch coil (which was not bad before) and no change.
But, its Bosch ignition coils had a defect and were being recalled.
One of my Bosch coils went bad within 13 months. Probably would have happened with Delphi for all my luck. Nevertheless, I returned all six to FCPEuro for lifetime replacement warranty.
