easiest way is to unplug the 2 plugs in the air filter intake hose. Then pull the plastic tube out. Then loosen the clamp on the intake and the one on the other end near the air filter. Take off the rubber hose between air filter and intake. Then unclip the 2 clips on top and pull cover off. Reverse for install. Just make sure to plug wires back in or your check engine light will come on.How to change a air filter on 2002 buick century?theres a tube that runs from the throttle body,take it off and then you will see a square box,you should see at least 3 of 4 screws,take them out and lift the cover,and there it is.How to change a air filter on 2002 buick century?remove the top( possibly clamps and hold down nut) remove old filter, clean out box, install new filter, replace cover.
