MG HS 2.0 Turbo (2026): Engine Air Filter Replacement

The 2.0 Turbo air filter sits in a plastic housing in the engine bay and can be replaced without removing the engine or the intake tract. It is usually replaced every 10,000-15,000 km (6,000-9,000 miles), and more often in dusty conditions. The exact cover design (clips or screws) depends on the market and trim level. Below is a general procedure that fits a housing of this type.

Difficulty: Easy Time: 15-20 minutes Steps: 8 Tools: Torx or Phillips screwdriver (if the housing cover is held by screws), flat-head screwdriver, vacuum cleaner or dry rag

Part

🔩 Engine air filter for the MG HS with the 2.0 turbo engine (20L4E). The exact OE part number is not confirmed, so only the part is named here. Aftermarket equivalents are available from K&N (33-2153, but this is a low-restriction performance filter, not a standard paper replacement), Mann, Mahle and Filtron

Step by step

8 steps

Shut off the engine, let it cool down and open the hood. Locate the black plastic air filter housing at the side of the engine. The air intake duct connects to it, and from there the air goes on to the turbocharger.
Inspect the cover. Release all the clips around the perimeter or remove the retaining screws. If the cover has an airflow or temperature sensor connector on it, you do not need to disconnect it.
Lift the cover and move it aside, without stretching the ducts and wiring. If a duct clamp is in the way, loosen it.
Note how the old filter is seated, and lift it out.
Clean the inside of the housing with a vacuum cleaner or a dry rag. Make sure no debris falls toward the intake duct leading to the turbocharger.
Place the new filter exactly into its seat. The sealing rim must lie flat around the entire perimeter, with no distortion.
Put the cover back on, make sure it is seated tightly, and secure the clips or screws. If you removed a duct clamp, tighten it (do not guess a torque value; a secure tightness without stripping the thread is enough). Check that the connectors and ducts are in place.
Start the engine and listen for a hissing sound from an air leak. Make sure there are no warning messages on the instrument cluster.

Common mistakes and warnings

A cover that is not sealed properly or a misaligned filter lets unfiltered air reach the turbocharger and can damage its blades. Do not use oiled low-restriction filters on engines with an airflow sensor without understanding the consequences: excess oil contaminates the sensor and causes error codes and rough engine running. The exact cover fastening design on your version may differ, so inspect the housing before starting work and do not force the clips.
