About this product
When charge air cooler performance matters, the HART 603 736 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Core Length [mm]: 185 mm, Core Width [mm]: 188 mm, Core Depth [mm]: 85 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with AUDI, SEAT, SKODA, VW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 1J0.145.803 A, 1J0145803A, 1J0145803B, 1J0.145.803 F and 4 more. Matching these numbers confirms a like-for-like replacement with no loss of function. HART is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
