The DIY guide for the e90 spark plug change that I linked above is extremely well written and the entire process is not difficult as long as you have some basic wrench turning skills. If you've removed your front cabin air filter and windshield cowl before, the job should take no more than one hour.

Based on my research on this forum, once one coil fails, the others are not too far behind. For a while I kept a spare coil in my garage, the time came to use it a few months ago, and literally the next day another failed.
