MVS Volvo Forums ninja instarx asks a great question: why the practice of securing the MAF sensor with security screws?
“Bought a new MAF and what a difference! Easy starting, smooth running.
But what’s up with the 5-point security screws that mount the sensor? Why does Volvo think its so important to not unscrew it? It’s just a sensor inserted into a plastic collar.
I ask because my replacement MAF assembly has a diameter that is a bit too large to fit into my filter housing and air duct (I had to duct tape it in place). I want to put the new sensor into the old assembly, but there are those darn 5-point security screws. Why does Volvo think that never removing that part is so critical?”
