2 Answers
The method for replacing the air filter element in a Classic Focus is as follows: 1. Remove the fuse box cover under the front passenger seat; 2. Take off the vertical inner cover of the fuse box; 3. Pull out the old cabin air filter; 4. Install the new cabin air filter in reverse order. The Focus is a brand under Ford Motor Company of the United States, available in both sedan and hatchback models. Taking the 2021 Focus as an example, its body dimensions are: length 4647mm, width 1810mm, height 1468mm, wheelbase 2705mm, fuel tank capacity 53 liters, trunk capacity 511 liters. It is equipped with a 1.5L naturally aspirated engine, with a maximum power of 90kW and maximum torque of 153Nm.
I often help my friends with the air filter replacement for their Focus. Here's a brief rundown of the process: First, open the engine compartment and locate the air filter box. For the classic model, it's on the right side near the windshield, a rectangular black box. When releasing the spring clips around it, avoid using brute force—pinch the middle and gently pry for the least effort. Lift the cover to remove the old filter, being careful not to let leaves or debris fall into the intake pipe. Install the new filter in the same orientation, ensuring the rubber edge fully seals against the box edge. When closing the lid, align all four corners first; you'll know it's secure when you hear the clips 'click'. For those frequently driving on dusty roads, it's recommended to change it every 10,000 km, while normal road conditions allow for a 20,000 km interval. Doing it yourself saves over 300 yuan compared to a dealership service.
