The 40mm dimension was specifically chosen with the main radiator in mind: a thicker core would restrict airflow to the radiator positioned directly behind it, potentially compromising engine cooling under sustained hard use. At 40mm, the heat exchanger achieves maximum cooling capacity without that trade-off. In testing, the system produced an average 9°C reduction in water temperatures to the intercooler across the RPM range, enabling the intercooler to deliver an additional 6°C average reduction in intake air temperatures versus the stock setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e+\u003c\/strong\u003e 60% more volume and 19% more face area vs stock heat exchanger\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e 40mm core thickness vs 24mm OEM, sized to preserve main radiator airflow\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Average 9°C reduction in water temps to intercooler across RPM range\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Additional 6°C average reduction in intake air temps vs stock\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Reduces heat soak to maintain peak power during sustained aggressive driving\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Fits BMW F87 M2, F80 M3, and F82 M4 with S55 engine\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":51268707713270,"sku":"DNND780-0001A","price":749.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/57a5d36b4f864ca7071d80ca42c277dfL.jpg?v=1784135647","url":"https:\/\/autotecknic.com\/products\/dinan-high-performance-heat-exchanger-bmw-f8x-m2-m3-m4","provider":"AutoTecknic USA","version":"1.0","type":"link"}
