proudly offers VRSF Competition HD Intercooler Upgrade for 2012–2017 BMW M5/M6 F10/F12/F13 S63. Replace your inefficient factory intercoolers with the VRSF Competition HD Intercooler Upgrade Kit to get the most out of your tuned S63. We designed this kit to be one of the best performing, direct bolt on intercoolers available for your BMW with special attention to quality and performance while maintaining a reasonable price. Our intercoolers allow for higher HP gains, mainly due to their ability to keep intake temps down while preventing heat soak which is a common problem with the factory intercoolers. This results in a more power and increased reliability with reduced chances of pre-detonation & knock. The most important component of any intercooler is the core. The core cools the charged air from the turbo before it enters the engine and the OEM BMW tube and fin intercooler is designed to support low boost levels and air flow. Once boost levels and air flow are increased, the OEM intercoolers are easily overwhelmed and can not keep up with the cooling demands of a tune running more than OEM boost levels. This results in heat soak which will result in a power loss and a higher potential for pre-detonation in the upper RPM range. We remedy this problem with our custom bar and plate core design which utilizes a staggered and offset high density internal and external fin pack. Our proprietary VRSF Competition HD core has been carefully tuned to provide the the best intake temperature reduction while maintaining minimal pressure drop along with our CFD optimized cast end tanks. Every VRSF product includes our lifetime warranty & our “No Hassle” satisfaction guarantee which includes fitment & defects. Each VRSF intercooler is hand finished and pressure tested to ensure a high quality, leak free experience. These are also a great upgrade for those interested in upgrading from the leaky OEM intercoolers and they are a direct replacement for your factory intercooler and fully reversible. All required hardware is included. This part replaces OEM BMW factory part numbers 17517843119 & 17517843123
