i want to get my 99 nissan altima a cold air intake.. which one would be best for my little 4 cylinder ridE?

Generally, a CAI is a CAI. The ebay knockoffs do just as good a job as the namebrand stuff like AEM and Injen. Brand doesn't really matter. The only thing to worry about really is what air filter is used especially with the knockoffs. Then you do need to get something good like K & N or something.
