Review on Airaid Cold Air Intake System: Boost Horsepower, Advanced Filtration - 2007-2011 JEEP (Wrangler, Wrangler III) Compatible - AIR-310-208 by David Naranjo

I have a 2007 Jeep Wrangler Unlimited X (4-door) with about 69,000 miles and I wanted to improve fuel mileage after changing to 285/70/17 tires. I did a lot of research and finally decided on the Airaid 310-208. My fuel economy was around 11-12 mpg city and 15 mpg highway at best. I installed this air intake and had some pretty drastic changes in gas mileage. I jumped to 15-16 mpg city and about 19 mpg highway. Although that's not the only difference I noticed. If you're a Jeep owner, you've probably experienced a "sluggish overpass" on the freeway and trouble maintaining 75 mph. This product didn't completely fix the problem, but it made it MUCH better! I will tell everyone I know this is a great product and will pay for itself very quickly.
