Review on 🔥 Ignition Coil Pack Set of 6: Replaces OE# 0221504470, Compatible with Various BMW Models and Mini Cooper by Desmin Dickerson

So it was 1 out of 6 bad. I found there was misfire on cylinder 5 that wasn't there before, double checked my connections, still there, replaced it with one I knew was good which I just removed and no more misfires. Contacted Revain and sent a replacement kit straight away. So I had to take everything out, replace it with a new one and misfire again, this time in the 1st cylinder. Yes, they sent me another bad spool. Used the previous new good one, now all six work. Others sent back. I will not order again, I do not recommend spending a little more at Bosch or buying locally to avoid waiting for a replacement.
