Enhance Engine Performance with the Airaid 300-637 Air Intake System Review

Excellent product, cheaper than other brochures (Quadratec, Summit). Available for 2013 JKU and purchased with Airaid Intake. Nice sound, MPG increase (1-2 MPG difference, consistent across multiple fills). Has the same effect as a minor exhaust upgrade!

I bought this and a K&N CAI at the same time hoping to get the combined effect of improved performance and mpg on my 2012 Durango Crew 3.6 VVT. I did a lot of research while they were coming, then installed K&N CAI to see how it worked and checked the claims people were posting online. After being convinced by the performance, sound, throttle response and increase in fuel economy per gallon I was very…
