you best bet is to save your money on these little bolt ons here and there that might give you 25-30 more hp for 1000 - 1500 dollars and get the cobra killer kit from tim at t&j performance and put down some real power....... just my .02 cents.
I'd go that route but most people in here don't have that kinda money to fork into their cars. For me bolt-ons are nice and let me have more fun with the ride.
