Cheap Peugeot 508 Intercooler

Yes, but only on turbocharged engine variants — every 508 diesel (such as the 1.6 BlueHDi, 2.0 BlueHDi, and earlier 1.6 HDi and 2.0 HDi units) is turbocharged and therefore fitted with an intercooler, and the petrol turbo engines (such as the 1.6 THP and later 1.2 PureTech and 1.6 PureTech) also carry one. If you had a naturally aspirated petrol 508 the intercooler would not be present, but in practice the vast majority of 508s on UK roads are turbocharged diesel or turbo petrol models, so an intercooler is a very common part on this car.

The 508 Mk1 ran from 2011 through to 2018, with a facelift introduced in 2014 that brought some mechanical and ancillary revisions, so a 2012 (pre-facelift) and a 2016 (post-facelift) car sit either side of that boundary. Fitment within the same engine code is your best guide — if both cars share an identical engine code (found on your V5 or a VIN check), the core intercooler unit may well interchange, but mounting brackets and pipework can differ between pre- and post-facelift cars. Confirm the specific part against your registration with the breaker before buying.

Yes — the 508 Mk2 launched in 2018 as an entirely new generation on a different platform, with a revised engine line-up including the 1.5 BlueHDi, 2.0 BlueHDi, 1.2 PureTech and 1.6 PureTech, so its intercooler is not interchangeable with Mk1 parts. Always match by engine code first; the two generations share no direct mechanical carry-over on this component. Give the breaker your registration and engine code to be certain you receive the right unit.

No — trim level does not affect intercooler fitment on the 508; Access, Active, Allure and GT cars fitted with the same engine code will use the same intercooler. Trim determines interior specification, paint and cosmetic features, not the intercooler specification. Focus your search on matching the engine code and fuel type, and ignore the trim badge entirely.

Engine code is the key detail here, not just the displacement and fuel type — the 2.0 HDi family covers several distinct engine codes across the 508's production run, and the intercooler specification can vary between them. Pull the engine code from your V5 logbook or a VIN check and quote it to the breaker, who can cross-reference their stock accurately. This is the single most useful piece of information you can supply when enquiring about a used intercooler.

For the intercooler itself, gearbox type is not normally a determining factor — the intercooler is part of the intake/charge air circuit and is driven by the engine specification, not the transmission. However, if the breaker's intercooler comes with associated pipework or brackets, it is worth confirming these are compatible with your car's layout, as ancillary fitment can occasionally vary. Quote your engine code and registration to the breaker to be safe.
