The panel / cylindrical air filter is commonly referred to as "replacement air filter". It is installed in the vehicle's original airbox to replace the OEM air filter. It is made of highly performing materials that allow an increased air flow combined with a more efficient filtration, designed to ensure containment of all impurities from as small as 7 microns (compared to OEM's 10 microns).

This chart has a pure illustrative purpose and does not refer to the present filter.
BMC air filters are produced using a "Full Moulding" system that enables the characteristic red filter to be realized from a single mould with no welded joints thus avoiding easy breakage.
The rubber used in BMC air filtering systems has a long life, is very durable and has optimum adhesion characteristics to all shapes of airboxes.
BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity.
All BMC air filters are pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit.

DIY Guide: Performance Air Filter for Mercedes Benz C-Class SLK-Class (2001-2007) 3.2L for 2001-2007 Mercedes Benz C-Class SLK-Class 3.2L
Required Tools
- T25 Torx driver or bit socket
- 1/4-inch ratchet and extension
- Flathead screwdriver (for intake snorkel clips)
- Shop vacuum and microfiber towel
The M112 3.2L engine uses a dual-filter airbox integrated into the top engine cover (requires 2 filters total). Be gentle when pulling the cover upward off the four rubber mounting grommets, and ensure the rear Y-pipe seal sits flush on the throttle body or MAF housing during reinstallation to prevent vacuum leaks.
Phase 1: Factory Component Removal
- Unclip and slide back the two flexible plastic intake snorkel tubes located at the front left and right corners of the engine cover.
- Pull the front engine cover trim straight up, then firmly lift the main airbox assembly upward to release it from its four rubber mounting grommets and rear intake housing.
- Flip the airbox assembly upside down on a clean workbench and remove the perimeter screws securing each filter housing lid using a T25 Torx driver.
- Remove the old paper filters and vacuum out any leaves, sand, or debris trapped inside the lower airbox chambers.
Phase 2: Aftermarket Installation
- Drop the new pre-oiled red rectangular panel filter into the airbox tray, ensuring the molded red rubber perimeter flange seats completely flat inside the sealing channel.
- Reinstall the plastic filter cover lids and tighten the T25 Torx screws snugly in a crisscross pattern; do not overtighten into the plastic threads.
- Align the rear of the airbox assembly over the central intake opening, then press down firmly on all four corners to lock the cover onto its rubber mounting pins.
- Reconnect both front air inlet snorkels and snap the front engine trim cover back into place.
