With a setup where engine coolant is also re-routed through the heat exchanger, the system effectively assists in overall engine cooling as well as charge cooling. However, like its predecessors, it has room for improvement as it can be overwhelmed when the system is taxed aggressively or as power levels are increased. Once overburdened, this results in the undesirable outcome of power being diminished.  Avoidance of this unwelcome scenario can be attained though with a Dinan heat exchanger that improves the overall thermal management system so everything runs cooler and more efficiently while being budget friendly.\u003c\/p\u003e\u003cp\u003eThe Dinan B4x\/B58 heat exchanger for the BMW G2x\/G4x and Toyota A9x Supra assists in improving overall charge cooling using a more robust core (45mm thick Dinan core vs. 26.75mm thick OEM core) that wields 68% more heat transfer surface area for improved cooling capacity.  The significant increase in core thickness and full-size end tanks contribute to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a nearly 12º reduction in charge air temps recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment!\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAverage of 8.7º C reduction in charge air temps with a maximum reduction of nearly 12º C over 30 successive WOT pulls\u003c\/li\u003e\n\u003cli\u003eGeneral improvement to the efficiency of the thermal management system, inclusive of engine cooling\u003c\/li\u003e\n\u003cli\u003eDurable bar and plate design that is less susceptible to damage from road debris\u003c\/li\u003e\n\u003cli\u003e45mm thick Dinan core vs. 26.75mm thick stock cooler core\u003c\/li\u003e\n\u003cli\u003ePressure tested, 100% TIG welded, Aluminum construction\u003c\/li\u003e\n\u003cli\u003eReduces the tendency to heat soak \/ go in to limp mode\u003c\/li\u003e\n\u003cli\u003eDirect fit replacement with no modifications required\u003c\/li\u003e\n\u003cli\u003e68% more cooling surface area and volume than stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\u003cdetails style=\"margin-top:4px;\"\u003e\u003csummary style=\"cursor:pointer;\"\u003eFits 2 makes, 2019-2026 — click to view all 18 models\u003c\/summary\u003e\u003cul style=\"margin-top:8px;\"\u003e\n\u003cli\u003e2022-2026 BMW 230i\u003c\/li\u003e\n\u003cli\u003e2023-2026 BMW 230i xDrive\u003c\/li\u003e\n\u003cli\u003e2019-2026 BMW 330i\u003c\/li\u003e\n\u003cli\u003e2019-2026 BMW 330i xDrive\u003c\/li\u003e\n\u003cli\u003e2021-2026 BMW 430i\u003c\/li\u003e\n\u003cli\u003e2022-2026 BMW 430i Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2021-2026 BMW 430i xDrive\u003c\/li\u003e\n\u003cli\u003e2023-2026 BMW 430i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2023-2026 BMW M240i\u003c\/li\u003e\n\u003cli\u003e2022-2026 BMW M240i xDrive\u003c\/li\u003e\n\u003cli\u003e2020-2026 BMW M340i\u003c\/li\u003e\n\u003cli\u003e2020-2026 BMW M340i xDrive\u003c\/li\u003e\n\u003cli\u003e2021-2026 BMW M440i\u003c\/li\u003e\n\u003cli\u003e2022-2026 BMW M440i Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2021-2026 BMW M440i xDrive\u003c\/li\u003e\n\u003cli\u003e2022-2026 BMW M440i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2019-2026 BMW Z4\u003c\/li\u003e\n\u003cli\u003e2020-2026 Toyota GR Supra\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/details\u003e\u003cp class=\"pst-note\"\u003e\u003cem\u003ePlease verify exact fitment (engine, submodel, and trim) before purchasing.\u003c\/em\u003e\u003c\/p\u003e\u003cp class=\"pst-note\"\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e D780-0003\u003c\/p\u003e\u003cp style=\"color:#666;font-size:0.9em;\" class=\"pst-note\"\u003eImages are for illustration purposes only; actual product may vary.\u003c\/p\u003e\u003cp style=\"color:#cc0000;\" class=\"pst-warn\"\u003e\u003cstrong\u003eEmissions Note:\u003c\/strong\u003e This product is not CARB approved.
