Spark plug BRISK or OEM Audi

I got mine from ECS: drop-in replacement and no issues even with my Burger unit on map 2.

I currently run the Brisk er12s and have been happy with them...I'm mpi running full e85 and the car responds well. It's also what my tuner recommended.

I got a set of APR coils and Brisk Silver Racing ER12s plugs for around 200

I run 0.024 but I’m running Brisk plugs in my car on a custom tune. They’re pre-gapped to 0.026 and anywhere between those two would work fine for my specific plugs.

I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.

Overall, the power delivery is great.
