"I have 2012 Chevy Coly w/ 3.7L I5. I got this to add a bit more ponies and torque to tow a 19 Ft. Hybrid Travel Trailer. I have taken the trailer w/o the install and she did lag a bit...but doable. I have yet to go out since the install BUT even w/o towing, I feel the added power & torque and see an extra 1 to 1.5 miles per gallon of petro. I purchase a lot from AutoAnything and the Customer Service is just Fantastic. Thanks +" —James P from Southbridge, MA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2013 GMC Sierra, 3.7L 5-cyl. engine.
