The flow bench tested design of the JET Mass Air Sensor provides airflow increases of up to 45 percent and installs in 10 minutes or less. Jet Performance Products is a proven leader in automotive tuning technology.
I ordered JETS MAF to install it on my 2012 GMC Sierra 1500. After receiving the MAF I installed it and drove the truck to work the following day. Truck ran ok but it did have several noticeable hiccups that only seemed to get worse the more trips back and forth to work I made. I took the truck to my custom tuner to see what he could do to make adjustments to make the truck run better. I left the speed shop that day with my factory MAF sensor re-connected with a new $250 or however much paper weight. My recommendation is buy and replace with the factory sensor if yours fails.
