Default Spark Plugs? Which ones are best for me?

So recently my cousin bought a 2007 GT/CS, its procharged and has full exhaust etc.

I just need to find out what spark plugs I should get for the best price and best quality... My cousin is having an issue, and in 1st or 2nd gear it sometimes pops really loud at high RPMS (maybe a misfire?) but the Check engine light came on and it said possible vacuum leak so he got it checked out and found one fixed it... and it still did it.

But hes just wanting to get new plugs now, could someone please help me out and refer me to some really good high quality plat tip plugs?

Thanks. Possibly the cables too.

I believe for a supercharged application, you will want Autolite HT0 if you have the "long" plugs. Look at the top of one of the coils and see if you have 3LE as part of the partnumber.
