Hi all,

I am in the process of changing the following sensors on my car.
The check engine light came one and highlighted one of the sensors so I thought I would change all of them in the general area: nothing has been changed in years.

Coolant temperature sensor Saab 9000 (with TCS)
Saab 9000 Intake air temperature sensor to 1995
Saab 9000 temperature gauge sender 1/8" NPT

I was advised that sometimes the MAF sensor can go bad, although I am not having any problems with at the moment so I thought I could just clean it for now.
After looking online it seemed an easy process of just removing the sensor and spraying it with a mass airflow spray but there does not seem to be anything to spray on the 9000 Aero, its just a little black box.
Am I missing something?

Any help would be greatly appreciated.
