The CAIs really only make more power above 7k RPM so this is not bang-for-the-buck improvement for most people. If we're talking bang for the buck for horsepower, HFCs are your best first move. If you want bang for the buck aesthetics (look and sound) AND horsepower, a CBE is the way to go but will cost you double to quadruple what you'll pay for HFCs.

An oil cooler will make the car sustainably trackable, but I've done multiple track days in cooler weather with no issues (hot days will have you doing cool down laps frequently). Clear bra will protect you from scratches at the expense of looking like you put a condom on your car.
