Mordoklej Has Astra 2.2 got one or not. I'm a bit confused now as some people say yes, some people say no. If not then doesn't changing to K&N air filter, derestricting airbox, bigger air intake pipe make the engine to run lean?
astra22bertoneauto it does have a sensor in the air intake pip but i think (dont quote me on this) this is for the air temp sensor.
JohnnyN The sensor in the intake pipe is the Air Intake Teperature Sensor. There is no Mass Air Flow sensor (MAF) but there is a Manifold Absolute Pressure (MAP) sensor located in the inlet manifold just below where the throttle body sits.
