Ford F77Z-9601-AA Air Cleaner Element Assembly

All air filter cover assemblies must be installed correctly or engine damage could occur. If the vehicle is driven in dust, the filter should be checked every3000 miles and replaced if it's dirty. In any case, the filter should be replaced at least every 30,000 miles, even if it looks clean. Loosen the hose clamp on the air intake duct, just after the MAF sensor on most models. Disconnect the MAF sensor electrical connector where necessary. Release the two locking clips/clamps on the cover. Lift off the cover while separating it from the air intake duct. Remove the air filter element by lifting it out from one edge. Wipe the inside of the air filter housing with a clean cloth. Place the new air filter element in the housing. Reinstall the cover and reconnect the air intake duct, note the tabs on one side of the cover. Press down on the cover to engage the locking clips or secure the clamps. Reconnect the MAF sensor, if necessary, and carefully tighten the hose clamp on the air intake duct.
