How do I add Horse Power to 2003 cadillac cts?

Question

I'm going to be buying a 03 CTS this weekend and I want to know what I can put under the hood to give it some extra horse's besides just cold air intake. Referrals to site would help but would greatly appreciate opinions on what I should add to the car.

Answer 1

one word: SUPERCHARGER! nothing works better at getting h.p. out of a car then that.

if you wanna go cheaper, get a cold air intake. they are like 100 bucks, but you will get like 10-20 more h.p. out of one.

Answer 2

i wouldn't by that car and get a lexus is instead they are better, look better, will last longer, and perform better.
