I am looking for a recommendation for new spark plugs for my 2008 SRT 8 Super Bee. I have been working with Sean Powell from Hemifever, he is great by the way, and he has sent me a few tunes. Based on the logs I sent him, it looks like I am due for a tune up. I am still running the original spark plugs with 85K on the car. I know they should have been changed a long time ago. Now the question is, which plugs?? Thank you!
