What is the recommended gap for a factory set up on a 2018 trackhawk?
Thank you. I ended up setting them up at .028 based on what I had found but I think it is running to rich. I get a lot of carbon out of the exhaust tips and the exhaust is only 1 week old. That's why I asked. I think I'll remove them and change them to .031 like you found to see what that does. Only things I have done is the air intake and exhaust changed to a Corsa extreme.Actually, I’m getting ready to do that myself and would like to know. From the hellcat forum the answer is .031” for factory plugs at 18lb-ft installation torque.
