Which will give the greatest gain, I have heard different opinions on each can anyone help?

 

Numerous opinions on this one. Two friends of mine with 2K Max's both dynoed on the same day, one with CAI and the other with the SI and the dyno came out exactly the same. They also did a run from 80mph and were dead even. It SHOULD be same on the 4th gen's but it's debatable, since I haven't witnessed it. The SI is probably a little cheaper and easier to install since you don't have to drill a hole in the fender.
My 2 cents....

 

get the c.a.i.. it looks a lot better and i believe it offers a little more power..

 

Thanks, I was just curious because I have heard negative things about CAI and was just wanted to get the most bang for my buck.

get a cai you gat a more power and it sound much better than a popcharger
