yes
I'm pretty sure you will find it right after the air cleaner and the air cleaner outlet tube, it measures the air flowing into the engine. it helps to determine how long to hold the injectors open....
something that can detect what direction the air is flowing
Its in the air Filter box of your car. Stop using K&NThe MAF sensor monitors the air flow into the engine and sends that info to the ECM.
It senses the amount of air being drawn into the engine and communicates with the computer to adjust fuel levels accordingly.
