The significant increase in core thickness requires unique \"L\" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15\u0026amp;deg IAT delta 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\u003eThe factory B4x\/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAverage of 8\u0026amp;deg reduction in IAT's with a maximum reduction of 15\u0026amp;deg over 15 successive WOT pulls\u003c\/li\u003e\n\u003cli\u003eInstallation hardware included (inclusive of xDrive specific transmission oil cooler brackets)\u003c\/li\u003e\n\u003cli\u003eReduces the tendency to heat soak \/ go in to limp mode\u003c\/li\u003e\n\u003cli\u003e48mm thick Dinan cooler vs. 27mm thick stock cooler\u003c\/li\u003e\n\u003cli\u003e78% more cooling surface area and volume than stock\u003c\/li\u003e\n\u003cli\u003e100% TIG welded and pressure tested\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 1 make, 2016-2021 — click to view all 18 models\u003c\/summary\u003e\u003cul style=\"margin-top:8px;\"\u003e\n\u003cli\u003e2017-2021 BMW 230i\u003c\/li\u003e\n\u003cli\u003e2017-2021 BMW 230i xDrive\u003c\/li\u003e\n\u003cli\u003e2017-2018 BMW 330i\u003c\/li\u003e\n\u003cli\u003e2017-2019 BMW 330i GT xDrive\u003c\/li\u003e\n\u003cli\u003e2017-2019 BMW 330i xDrive\u003c\/li\u003e\n\u003cli\u003e2016-2018 BMW 340i\u003c\/li\u003e\n\u003cli\u003e2017-2019 BMW 340i GT xDrive\u003c\/li\u003e\n\u003cli\u003e2016-2018 BMW 340i xDrive\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 430i\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 430i Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 430i xDrive\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 430i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 440i\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 440i Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 440i xDrive\u003c\/li\u003e\n\u003cli\u003e2017-2020 BMW 440i xDrive Gran Coupe\u003c\/li\u003e\n\u003cli\u003e2017-2021 BMW M240i\u003c\/li\u003e\n\u003cli\u003e2017-2021 BMW M240i xDrive\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 D780-0002\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.
