Just got my truck with 34k on it. I don't know if plugs were ever done so I'm going to do them. Right now I just have intake and exhaust done. Planning on tuning in spring. What plug would be best for now?

I would just get Ford Performances. I've heard aftermarket ones have had problems.

Yup, If you are not running a tune, just stick with the stock plugs. BTW, I am running NGK cold plugs with my tune and I haven't experienced any issues. So not sure who is reporting issues with aftermarket plugs.

I installed the colder 542's in mine totally stock. It runs perfectly smooth. Not sure if they are still available?
