"My wife won't drive my H3 (3.7L engine) because it is too sluggish. Last night we went out to eat and I took my H3. I had a chance to get on the throttle a little and she wanted to know what I had done to give it more pep. BTW, I was driving. All I have installed is the Mass Air Flow Sensor and an AirAid filter and throttle body spacer. I 100% recommend this product." —Brad S from Cedar Park, TX bought a Jet Power-Flow Mass Air Sensor for a 2007 Hummer H3, 3.7L 5 cyl engine, 8th digit of VIN = E.
