Cheap Mercedes-Benz GLS Air Filter

Yes, every variant of the GLS has an air filter regardless of engine type — petrol, diesel, or the mild-hybrid and plug-in hybrid versions all draw in air through a filtration system, so this is a genuine and universal part across the range. Even the AMG-badged GLS 63 uses an air filter, just potentially a different housing configuration to the standard engines. The key variable is which air filter fits which engine, so your engine code is the most important detail to have to hand.

Almost certainly not — the X166 and X167 are entirely different generations with different engine families, intake systems, and airbox housings, so the air filters are not interchangeable across that 2019 boundary. Even where an engine designation looks similar on paper, ancillary components including airbox design often changed between generations. Confirm the part against your registration with the breaker before purchasing.

No, trim level does not affect air filter fitment — whether your GLS is a standard AMG Line, AMG Line Executive, or AMG 63, the air filter is determined entirely by the engine code and not by how the car is badged or specced on the inside. You may find cosmetic differences in the engine bay area depending on trim, but the filter element and housing are engine-driven choices. Supply your engine code (found on your V5 or via a VIN check) and the breaker will match you to the right part.

Yes, fuel type is a meaningful variable — a diesel GLS such as a 350d and a petrol GLS such as a 400d or 580 will have different engine configurations, airbox designs, and filter shapes, and the parts are not interchangeable between fuel types. Even within the same generation, different engine codes mean different filters, so two cars of the same model year can need completely different parts. Always confirm the engine code rather than relying on the badge or fuel type alone.

Both sit within the X167 generation which launched in 2019, so there is a reasonable chance the air filter is compatible if the engine codes match, but ancillary and housing changes can occur mid-production without obvious external signs. The engine code is the critical check here — if both cars share the same engine code, compatibility is more likely, but you should confirm this with the breaker against your registration to be sure before buying a used part.

Gearbox type is generally not the primary driver for air filter fitment — the filter is part of the intake system and follows the engine code rather than the transmission. That said, some engine and gearbox pairings were exclusive to certain markets or variants, so the engine code remains the single most reliable identifier for getting the right filter. Share your full engine code and registration with the breaker and they will cross-reference it correctly.
