Great air intake system! I already have one on my Dodge 1500 pickup and you can tell the difference right away. Next is my 2SS Camaro and I cant wait. Great products!

As always, the Customer Service was great. I install the Filter on my 2007 Dodge Ram Quad Cab long bed Pickup Truck. I changed the OEM air intake 2010. The system has provided the performance as advertised. I am very satisfied with my decision to make the change.
