I have a 88 camaro rs with a 2.8L engine and I was think on getting a cold air intake kit for my engine. What kit would I get and what site its that at? And is it easy to install? And is there a cold air intake that would fit the rs engine?

And its there any thing else I can add to my car that would give it more horsepower? Like a
Turbocharge or a supercharge which is cheaper and easyer to install?
Thank you for the help
