You'll see a decent gain from that. I'd say about 15-20 HP, but definitely a difference for an easy swap that seems to be inexpensive. Your car should have 19# injectors from the factory so that won't make any difference BTW. Just remember that you will need to probably get a new elbow for the throttle body. I think the stock intake on your car has the elbow on it as a single piece so you'll need to find an aftermarket one somewhere else.
