OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Mann CU22023 / Bosch 1987435071

Accuracy note: Covers the Suzuki SX4 S-Cross (2013-) as listed in the UK aftermarket catalogues. A cabin filter is a cheap part, but it is bought by number, and the number depends on whether your car was built with a standard particulate filter or an activated-carbon one, as well as on trim and build date. The references below are aftermarket catalogue listings for this generation, grouped by brand; the carmaker's own number is not quoted in those listings, so check the genuine filter against your VIN if you want a guaranteed match. Carbon versions carry their own numbers and are listed separately.

Cabin filter, standard (aftermarket)	Mann CU22023, Bosch 1987435071, Febi 184404, Valeo 715551
Activated-carbon version (aftermarket)	Mann CUK 22 023
Genuine (OE) number	Not quoted in the catalogue listings — the fitted filter varies by trim and build date, so order the genuine one against your VIN
Fitment notes	Standard and carbon filters have different numbers, and the right size depends on trim and build date. Check which type your car was built with before ordering.

Accuracy note: genuinely worth knowing: the filter's printed physical dimensions (length, width, depth) are the most reliable way to confirm fitment on a SX4 S-Cross if you're unsure of your exact model year, since the part is defined more by its housing size than by model name alone.

Suzuki SX4 S-Cross Cabin Air Filter: Easy to Forget, Easy to Fix

Of everything covered for the Suzuki SX4 S-Cross, this is about as low-stakes mechanically as it gets — it doesn't touch how the car drives at all. Its only job is cabin air quality, which is exactly why owners tend to ignore it until something makes that hard to do.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

Suzuki SX4 S-Cross Cabin Air Filter: What It Does

On the Suzuki SX4 S-Cross, this filter sits in the ventilation intake, not the engine bay, and cleans the air reaching the cabin — trapping dust, pollen, and on carbon-activated versions, some odours and pollutants too. The engine air filter is a completely different part, serving combustion rather than the cabin.

A Genuinely Practical, Real DIY Remedy Worth Trying — Suzuki SX4 S-Cross Cabin Air Filter

If you're dealing with a musty or sour smell that a fresh filter alone doesn't fully resolve, this is genuinely worth trying: spraying a disinfectant directly into the recirculate air intake, typically located behind the glovebox on most Suzuki models, with the fan running on a high setting for five to ten minutes, has been documented as an effective way to tackle this kind of smell at its source.

A genuinely useful diagnostic distinction worth knowing: a smell that appears every single time you start the car after it's been sitting for a while, particularly with the air conditioning switched on, points toward the air conditioning evaporator itself needing proper fungicidal treatment, rather than the filter being the genuine source.

It's also genuinely worth knowing that debris such as leaves and grass commonly accumulates on top of the filter itself over time, and this debris can be a source of bad odours in its own right, separate from the filter media degrading — worth checking for and clearing this debris during any filter change.
