Q: How to Remove the Air Filter Box on a Jeep Wrangler?
A: To remove the air intake assembly on a 2.5L engine, start by detaching the cable from the negative battery terminal. Remove the air filter and lift the clips or band clamp. Detach the warm air hose and label and remove any vacuum hoses. For a 4.0L engine, detach the cable and flexible air duct. Label and detach all vacuum hoses and detach the heat riser tube. Remove the upper half of the air filter box lid and the air filter element. For a 4.2L engine, detach the cable and flexible ambient air duct. Remove the wing nut, cover, and filter element. Label and detach all hoses from the air filter box. For V6 engines, detach the cable and remove the engine cover. Disconnect the IAT sensor connector and loosen the crankcase ventilation hose. Loosen the clamp and disconnect the hose. On 3.6L engines, detach the coolant hose from the retainers. Remove the mounting bolt(s) and lift the air filter box. Firmly pull the air filter box, lid, and intake hose upwards to disengage the pin(s) and remove from the vehicle.
