Do not buy an aftermarket coil. A waste of money and the stock coil is more than adequate. Don't buy an SRI. They suck hot engine air and cost you some hp/tq. Do get a K&N drop in filter. It drops into the factory airbox which doesn't suck in hot engine air. You won't notice a power increase, but you won't lose any either. You'll also notice a faster 1st to 2nd shift in the automatic. The lull between gears 1-2 will be gone. There aren't any decent chips out there for the na PT and the ones on ebay are garbage.
