In this system, the charge air is cooled via a separate cooling water circuit. Reducing the coolant temperature is therefore the key to improving charge air performance and ensuring that the engine can deliver its full rated power even during sporty driving. The Wagner Tuning upgrade water cooler solves this bottleneck by increasing the volume by 55% and the depth (from 25 mm to 40 mm).\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTechnical data in direct comparison (OEM vs. Wagner Tuning)\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eThe Wagner Tuning auxiliary water cooler offers decisive advantages over the standard cooler:\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eVolume:\u003c\/b\u003e\u003cspan\u003e With 13.52 liters, the Wagner Tuning cooler offers 55% more volume compared to the OEM cooler with 8.73 liters.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eDimensions (depth):\u003c\/b\u003e\u003cspan\u003e At 40 mm deep, the Wagner Tuning unit is significantly thicker than the standard cooler at 25 mm.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eCooler core:\u003c\/b\u003e\u003cspan\u003e A high-performance competition racing intercooler core is used.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOEM water cooler dimensions:\u003c\/b\u003e\u003cbr\u003e\u003cspan\u003e720 mm x 485 mm x 25 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eV = 8.73 liters\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eA = 3492 cm²\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWagner Tuning water cooler dimensions:\u003c\/b\u003e\u003cbr\u003e\u003cspan\u003e690 mm x 490 mm x 40 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eV = 13.52 liters\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eA = 3381 cm²\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eVehicle compatibility (Audi RS4 B9 \u0026amp; RS5 F5)\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eThe Wagner Tuning Competition water cooler kit is plug-and-play compatible with the following models with the 2.9L V6 biturbo engine:\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eAudi RS4 B9 (331 kW\/450 hp, from 2017)\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eAudi RS5 F5 (331 kW\/450 hp, from 2017)\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePart number: 400001012\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eExperience the next level of performance with your Wagner Tuning water cooler kit!\u003c\/b\u003e\u003c\/p\u003e","brand":"Wagner Tuning","offers":[{"title":"Default Title","offer_id":53536023675221,"sku":"400001012.OEM","price":1318.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/3327\/0357\/files\/download_66a52cb8-3c76-4b51-ad89-262decffa596.webp?v=1774337500","url":"https:\/\/shop.regalautosport.com\/products\/wagner-tuning-audi-rs4-b9-rs5-f5-radiator-kit-oem-ic","provider":"Regal Autosport","version":"1.0","type":"link"}
