Used Ford Fiesta Air Filter

Air filters on the Fiesta follow the engine code far more closely than the model year, so the key question is whether both cars share the same engine code rather than simply the same year. The Fiesta has run through several distinct generations — Mk6 (2002–2008), Mk7 (2008–2017, facelifted 2013), and Mk8 (2017 onwards) — and even within a generation Ford used multiple engine families across petrol and diesel variants. Give your engine code (found on your V5 or a VIN check) to the breaker and ask them to match on that, not just the year.

The Mk7 ran from 2008 to 2017 and the Mk8 from 2017 onwards, and these generations use different engine families, so a straight swap across that boundary is unlikely to work. Even where an engine name sounds similar — for example a 1.0 EcoBoost — the specific code and airbox design can differ between generations. Confirm fitment with the breaker against your exact registration and engine code before buying.

No — trim level (whether that's Studio, Zetec, Titanium, ST-Line, or ST) has no bearing on which air filter your Fiesta needs. What matters is the engine code, fuel type, and model year within the generation. The only exception is the Fiesta ST, which uses a performance-tuned engine with its own specific code, so buyers should confirm that code with the breaker rather than just quoting 'ST'.

No — petrol and diesel engines use entirely different air filter housings and filter elements, so these parts are not interchangeable even if the cars are the same age and generation. A diesel Fiesta (typically running a TDCi engine) and a petrol Fiesta (such as a Ti-VCT or EcoBoost) need separate filters matched to their respective engine codes. Always supply your engine code to the breaker to make sure you get the right part.

The Mk7 Fiesta was facelifted in 2013, and while many engine codes carried across that refresh, there were also engine changes introduced around that time — particularly with the rollout of the 1.0 EcoBoost family. If both cars share the same engine code, the filter is very likely to be the same, but confirm with the breaker against both registrations to be certain, as ancillary mounting details can change mid-production.

It's a helpful starting point, but the engine displacement alone isn't quite enough because the 1.25 petrol was used across multiple Fiesta generations with slightly different engine codes and airbox configurations. Pull the engine code from your V5 logbook or run a VIN check — it's usually a two or three letter code stamped on the engine block as well — and give that to the breaker alongside your registration. That combination will get you an accurate match far more reliably than the badge figure alone.
