Stock turbo? If so I think stock heat range would be fine still. Especially if this is your daily driver.

Denso IKH22's or the OEM plugs (NGK ILFR7H if I remember the part number correctly) would be fine for you.

This^^^ when you put down 100hp over stock--then you can consider a cooler plug--no benefit other wise.
