OEM Part Number: confirm via VIN — cabin air filter (aftermarket) Bosch 1987435017 / Febi 100381

Accuracy note: Covers the Fiat 500X (2015-) 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)	Bosch 1987435017, Febi 100381, Valeo 715620, Blue Print ADL142505
Activated-carbon version (aftermarket)	Bosch 0 986 628 642, Febi 100363, Blue Print ADL142517
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.

A Genuinely Important Clarification Worth Knowing First — Fiat 500X Cabin Air Filter

This is genuinely worth checking before assuming a filter needs replacing: not every car in this range actually has a cabin air filter fitted at all — models without air conditioning may have only a blanking cover, with no genuine filter behind it. If you're struggling to find one, it's worth confirming your specific car actually has air conditioning fitted.

A genuinely useful technical explanation worth knowing about where mould smell originates: when the air conditioning is running, condensation forms on the chiller unit, and airborne spores can settle on this damp surface and grow there, rather than the filter always being the sole source of a musty smell. Periodically switching the air conditioning off and running the heater on full with the blower on maximum helps dry out the chiller unit and surrounding housing.

It's also genuinely worth knowing an honest, UK-specific access difficulty: on right-hand-drive cars, the steering column sits directly in the way of the filter housing, making this a genuinely more awkward job.

Fiat 500X Cabin Air Filter: Easy to Forget, Easy to Fix

On the Fiat 500X, this part sits in an unusual category: neglecting it changes nothing about how the car drives, so there's no natural prompt to replace it. It only affects the air you're breathing inside the cabin, which is why it's so often left well past its interval.

Fiat 500X Cabin Air Filter: What It Does

Every bit of air blown through the Fiat 500X's cabin vents passes through this filter first, which is what traps dust and pollen — plus some odours and pollutants if it's an activated-carbon type. It has nothing to do with the engine air filter, a wholly separate component built for the combustion side of things.
