The only “difficulty” I can foresee is the removal... According to Elsa, there is a special coil pack removal tool, which can be acquired through ECS Tuning for about 65 bucks. I’ve also seen the coil pack split during the removal but looks like the trick is to pull slow and steady.
I’ve felt a few minor misfires at idle and on acceleration and believe it will be “cheaper” to just replace both plugs and coils at once and avoid numerous back and forth trips to the dealer (with a likely reply of “couldn’t replicate the problem”) - time is money
