What’s up team, I have a few questions:

I have a 2022 B-GTS with around ~14k miles. I have a header back exhaust on it that connects to the stock muffler. I also have air filter on it with an OTS Cobb tune. I was having fun one day and I got some misfire codes - P0301, P0303, P0305.

I was thinking about getting one step colder plugs. Pros and cons with these cars???
