2.4L Cold Air Intake

Dose any one know of a Cold Air Intake for a 2.4L 4cyl Or have a idea for more power for little money

I've had 2 Nissan trucks and my current 2000 Frontier has a few improvements in the Cold Air intake and the Flowmaster exhaust, which affords me better mileage, more power, and a better throaty sound. write me if interested, [email protected] put Frontier in the subject line, I erase all other email
