The charge air is cooled via a separate cooling water circuit. Lowering the cooling water temperature is therefore the critical factor in maintaining engine performance, especially during aggressive driving or performance enhancements.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe Wagner Tuning upgrade water cooler solves this bottleneck with a 60% increase in volume, which is primarily achieved by increasing the installation depth (from 30 mm to 48 mm). The increased coolant volume keeps the entire system temperature at a lower level over a longer period of time – essential for the 480 hp to 550 hp models.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe Wagner Tuning Competition water cooler kit is plug-and-play compatible with the following models with the S58 engine:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBMW G87 M2 (460 hp, from 2023+)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBMW G80\/G81 M3 (Base\/Competition\/Touring, 480–510 hp, from 2021+)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBMW G82 M4 (Base\/Competition\/CSL, 480–550 hp, from 2021+)\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eTechnical data in direct comparison (OEM vs. Wagner Tuning)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe Wagner Tuning front water cooler offers decisive advantages over the standard part:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eVolume (V): From OEM 9.16 L to 14.67 L (increase +60%).\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDimensions (depth): From OEM 30 mm to 48 mm.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eArea (A): Remains the same (3055 cm²), with significantly greater depth.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eDimensions OEM water cooler:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e505 mm x 605 mm x 30 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eV = 9.16 liters\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eA = 3055 cm²\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWagner Tuning water cooler dimensions:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e505 mm x 605 mm x 48 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eV = 14.67 liters\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eA = 3055 cm²\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003ePart number: 400001021\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003ePrepare your BMW M for maximum performance – now with parts certification!\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Information:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis product is intended for performance use and should be installed by a qualified professional.\u003c\/p\u003e\n\u003cp\u003eIt is the customer’s responsibility to ensure compatibility with their specific vehicle prior to purchase.
