I am very impressed with the Volant air intake for my 2011 suburban. I can definitely tell it increased my power in the higher RPM range, looks great, and improved my gas mileage by at 1-2 miles per gallon. It is quiet at idle like stock but you can hear is sucking the air as the RPM's get higher. The truck is breathing much better. The installation wasn't bad. Very good quality. I am Very happy with the product.
The installation was not difficult. It is basically knowledge and common sense where it goes (yes, it comes with instruction). I have install the air filter with a scoop. it totally does improve the mileage, if you drive normal not press the gas and all of sudden you start pressing the braking. This COLD AIR INTAKE OF VOLANT is meant for truck/Suv.
