I picked up my 08 gt500.....563 miles 33k...bone stock..what do u guys suggest for cold air intake ?..Jlt looks like a nice setup....also...if I do a pulley ,tune, cai kit...will I need colder plugs and also will these engines easily handle the numbers they crank out....this car is brand new and I don't want to ruin it....I plan on a 373gear...could use that....thanks again guys
