"Coupled together with my secret weapon cold air intake by WEAPON R and my silver bullet throttle body spacer by AFE this MAF sensor by jet makes my intake pull in more air than without it. I can hear it when im doing 5 mph. Even when im idle the car sounds better like its ready to go.But I also had a full and complete tune up right before the install of my 3 aftermarket parts. No matter what kind of aftermarket intake you have and/or throttle body spacer definitely this part is a must buy. JET!!" —Ray M from Egg Harbor City, NJ bought a Jet Power-Flow Mass Air Sensor for a 2003 Chevy Blazer, 4.3L V6.
