How to Service the Air Filter Box on Ford Focus?

Service of the air filter box should begin when the vehicle sits in neutral position on a hoist. Start by eliminating the intake air resonator after unbolting the mass air flow sensor pipe clamp from the frame. One must disconnect the maf sensor electrical connector followed by removing the air filter box cover intake bolt and the two wheelwell-to-air filter box cover bolts before removing the air filter box cover. The air filter box assembly removal begins by eliminating the rearward bolts that connect the air filter box to the frame while you should also remove the forward air filter box-to-frame bolt. The maf sensor pipe requires clamp loosening to split from the air filter box and inspect the lower maf sensor pipe screen for detachment before resecurement to the maf sensor pipe. The reverse removal steps must be followed for relaying the equipment.

How is the Air Filter Box removed and reinstalled on Ford Focus?

The air filter box finds its place beneath the shield at the front of the left fender area on the frame. Place the vehicle in neutral mode on the hoist unit. The installation requires users to first remove the intake air resonator and mass air flow (MAF) sensor pipe clamp-to-frame bolt. Reinstall these components with torque at 12 Nm. Remove the LH fender well splash shield by disconnection of the MAF sensor electrical connector and removing 8 screws. Perform bolt removal of the air inlet tube before applying 9 Nm of torque (80 lb-in) while replacing it. Unwind the inlet pipe clamp then detach the pipe before restraining it by 4 Nm torque (35 lb-in), when reinstalling. Installation of the rearward air filter box-to-frame bolts should begin with 9 Nm (80 lb-in) torque while the forward air filter box-to-frame bolt will follow with the proper tightening. When reattaching the air filter box assembly with MAF sensor pipe users must torque it to a value of 9 Nm (80 lb-in). The lower MAF sensor pipe screen might detach and stay on the air filter box elbow but you should check it and reposition it properly to the MAF sensor pipe. The process ends by loosening the clamp before separating the MAF sensor pipe from the air filter box and tightening it to 4 Nm (35 lb-in) when reinstalling. The procedure for completion involves reversing all removal procedures.
