Spark plug ?
I am planning to replace my plugs while having some work done to my car. I know a lot of you guys run some NGKs, but I was told they are best on forced induction applications and with my setup, replacement AC Delcos are the most appropriate. With the following mods which plugs would you guys recommend: cam, headers/ full exhaust, CAI, p&p tb, tune.

Re: Spark plug ?
I would run one step colder than stock. Options include AC Delco 12571165, Bosch 4505, or NGKTR61X.
