As I had no idea when they were last replaced I figure it would be a good time. As well after chatting with EPL after everything was flashed it was recommended to replace the spark plugs. I went with the NGK PFR8S8EG gapped to 0.026" per their recommendation.
The install was very similar to my previous B5 S4. I had to move the coolant reservoir and stock air box out of the way to get to the coils, but wow are the coils a pain in the butt to pry out. I thought for sure I was going to break them trying to get them out. With the old plugs out they actually weren't in too bad of shape, but as I was already here I replaced them anyway.
Nothing too exciting with this post, but it is one less item to replace.
