Review on 🚀 Airaid Cold Air Intake System for 2009-2012 DODGE/RAM: Boost Horsepower with Superior Filtration – AIR-301-237 by Joseph Long

It took about an hour to install. The instructions were great and easy to understand even if you don't know anything about working with vehicles. The sound is amazing, a very noticeable low hum when you open the throttle. I haven't traveled long enough to determine if it helps with gas economy, but there is better throttle response. Put in a 2012 Ram 2500 Power Wagon 5.7 Hemi.
