MANN-FILTER Air Filters
The MANN-FILTER Air Filters is an engine air filter line, stocked through the AMSOIL catalog for service on vehicles and equipment that do not use AMSOIL-branded filters. MANN-FILTER is the global filtration brand of MANN+HUMMEL, a German engineering company that supplies original equipment filters to most major European vehicle manufacturers and stocks an aftermarket catalog of more than 6,800 filters covering over 300,000 vehicle and equipment applications. MANN-FILTER is widely specified for German vehicles (BMW, Mercedes-Benz, Volkswagen, Audi, Porsche) along with many Asian and domestic platforms.
Choose the vehicle or equipment first, then select the matching filter code for the exact year, make, model, and engine. The cross-reference result is what matters at order time.
What the line does
The MANN-FILTER Air Filters line handles preventing airborne dust, dirt, and debris from entering the intake tract and reaching the cylinders. Filtration at this point in the system is the deciding factor between long, predictable component life and premature failures driven by contamination that would otherwise reach internal surfaces.
Where the line fits
This line is used on passenger cars, light trucks, SUVs, vans, and equipment using a serviceable panel or round air filter element. The exact part number for a particular application is set by the lookup result for the year, make, model, and engine in question. Substituting a same-brand part with different dimensions or media because the part numbers look similar usually does not work; the cross-reference is specific.
How to find the right code
Confirm the right cross-reference for the vehicle or equipment in the AMSOIL filter lookup resources before ordering. The original-equipment filter part number from the owner's manual or the existing service record is also a good starting point and will usually return a clean cross-reference within this brand line.
Service recommendations
Replace the air filter at the vehicle manufacturer's recommended interval and inspect at every oil change. Severe operating environments (dust, gravel road, agricultural, construction) require shorter intervals. Documenting the installed part number and the service date in the maintenance log keeps future cross-references accurate and prevents confusion when similar codes show up under multiple brand lines.
About the AMSOIL alternative line
For applications where AMSOIL publishes a matching in-house filter, the matching engine air filter cross-reference for the vehicle or equipment is generally the preferred choice because it is engineered around AMSOIL synthetic lubricants and the extended-drain intervals those lubricants support. The MANN-FILTER Air Filters line is the right choice when the application is outside the AMSOIL filter coverage, when the OEM specifies one of these brands, or when the existing service record already runs this line and the maintenance program is already set up around it.
Order the MANN-FILTER Air Filters
The MANN-FILTER Air Filters line is sold through the AMSOIL catalog with individual cross-reference codes selected at order time. Filters are backed by the brand's standard warranty as supplied through AMSOIL. Confirm the right code for the vehicle or equipment with the AMSOIL filter lookup resources, then order the MANN-FILTER Air Filters.
Frequently asked questions
Why does AMSOIL stock MANN-FILTER Air Filters?
AMSOIL stocks the MANN-FILTER Air Filters line so customers running this brand on a particular vehicle or piece of equipment can order both the lubricants and the filters from the same supplier. For applications where AMSOIL also publishes a matching in-house filter, the AMSOIL line is generally the recommended choice; the MANN-FILTER Air Filters line covers the rest of the catalog where AMSOIL does not publish a matching cross-reference.
How is the right cross-reference number selected?
Match the year, make, model, and engine of the vehicle or equipment to the cross-reference in the AMSOIL lookup, or cross from the existing OEM filter part number. Substituting a same-brand part with similar dimensions but different media or fittings is not a substitute; the published cross-reference is what matches the application.
Will using a MANN-FILTER Air Filters affect a new vehicle warranty?
No. Using a published cross-reference filter that meets the OEM specification does not void a new vehicle or equipment manufacturer warranty. The Magnuson-Moss Warranty Act protects the owner from a warranty denial based solely on aftermarket part choice when the part meets the OE specification.
How often should this filter be replaced?
Replace the air filter at the vehicle manufacturer's recommended interval and inspect at every oil change. Severe operating environments (dust, gravel road, agricultural, construction) require shorter intervals. The actual interval depends on the application and the operating environment; severe-service conditions call for shorter intervals than the published baseline.
Can a MANN-FILTER Air Filters be used with AMSOIL synthetic lubricants?
Yes. The filter line and the AMSOIL synthetic lubricant program are independently engineered and work together without compatibility issues. When AMSOIL publishes a matching in-house filter for the application, that filter is generally the recommended choice for the longest-supported drain interval; otherwise this line is the right cross-reference.
Are these filters covered by warranty?
Yes. The MANN-FILTER Air Filters line carries the brand's standard warranty as supplied through AMSOIL. Defective parts can be returned through the AMSOIL Return Policy when unopened and within the published return window.
