Review on 🏎️ K&N Cold Air Intake Kit for 2005-2009 Mustang: Boost Horsepower, 50-State Legal, High Performance – Model 57-2566 by Edwin Kreps

Pays out for Air Intake

I can notice a difference in throttle response and drive about 1.4 amps better through Las Vegas. In my 2005 Mustang I've increased my mileage by 2mpg city and 3mpg before and after, but idling is identical so average Vegas driving at 1.4mpg is better after a full tank of 91/ premium.1, 4mpg @ 2.67/gal = 20 additional miles per tank of fuel and estimated ROI in 67 weeks. I would recommend this to others.

Pros
