Used Peugeot 307 Intercooler

Only the turbocharged diesel and turbocharged petrol variants of the 307 have an intercooler — naturally aspirated petrol engines do not use one. Common turbocharged engines found in the 307 include the 1.6 HDi, 2.0 HDi, and the 1.6 THP petrol, all of which have an intercooler as part of the forced-induction system. If your 307 has a non-turbo petrol engine such as the 1.4 or 1.6 naturally aspirated units, there is no intercooler fitted and you will need to check whether another cooling or air intake component is what you are actually looking for.

The 307 ran as a single generation from 2001 to 2008, with a facelift arriving around 2005 that brought some exterior and trim changes but did not fundamentally alter the engine range. Because intercooler fitment follows the engine code rather than the model year, a 2004 and a 2007 car running the same engine code — for example both being 2.0 HDi units with the same code — are likely to be compatible, but mounting brackets and ancillary connections can change quietly within a production run. Confirm the engine code from your V5 or a VIN check and verify the specific mounting arrangement with the breaker before buying.

Trim level does not affect intercooler fitment on the 307 — the intercooler is determined by which engine is fitted, not whether the car is badged S, SE, or XT. A 2.0 HDi in an S and the same 2.0 HDi in an XT will use the same intercooler, so do not worry about matching trim. What you should match is the engine code, which you can find on your V5 document or via a VIN check, and supply that to the breaker.

Engine code is the single most reliable detail for intercooler fitment on the 307 — the model carried several different diesel and turbocharged petrol engines across its life, and core dimensions, pipe connections, and mounting points can differ between them even if the fuel type and year overlap. For example, early 2.0 HDi engines and later 1.6 HDi engines are both turbodiesel but will not share the same intercooler. Always check your V5 or run a VIN check to get the exact engine code, and give that to the breaker rather than relying on year and fuel type alone.

Body style does not affect intercooler fitment; the 307 SW uses the same engines as the rest of the 307 range, so the intercooler is determined entirely by engine code. You do not need to specify estate or hatchback when searching — just supply the engine code from your V5 or a VIN check. Give that code to the breaker and they will be able to identify the correct unit.

Some PSA Group engines were shared across multiple models, so it is not impossible that certain intercooler units overlap between the 206, 307, and 308, particularly around shared HDi diesel engines. However, pipe routing, mounting points, and core dimensions are often model-specific even when the engine family is the same, so you should not assume a direct swap without checking. Give your engine code and registration to a knowledgeable breaker who can cross-reference whether a unit from another PSA model is a confirmed match for your specific application.
