The MAF is on the throttle body housing (where the rubber air duct connects to). It has 3 phillips screws and an electrical harness.

Why do you feel the need to pull it? Getting an error for it? Sometimes the electrical contacts get debris on them and after being cleaned the MAF will function correctly. MAF and electrical parts cleaner is available through some auto stores.

Just don't use carb or throttle body cleaner on it as its very delicate.

Default MAF

A Q Tip and isopropal alcohol will do.

It'* the large square sensor on your TB.

TB/MAF cleaning is covered in Techinfo. Link at the top of the page.
