Some of the biggest issues when owning a BMW can come from cooling system components. Even through years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N52/N54/N55/N20 engine sees failure at the plastic cylinder head outlet adapter connecting the cylinder head to the thermostat hose. The stock plastic adapter simply shears off at the end of the barbed fitting, creating a massive coolant leak. The engineering team at ECS Tuning decided a billet aluminum piece was a much better option to contend with the temperature fluctuation. Since other offerings on the market want you to modify your OE hose to be reused, they even developed a silicone replacement hose. These 2 pieces can be purchased separately if you decide to reuse your existing OE hose or in a package kit together for a single click upgrade. Features: Manufactured from billet 6061-T6 with type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic ​​Will not become brittle and fatigued over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Follows OEM form for perfect fitment. Utilizes (and includes) OEM O-ring 11537545278 to ensure a proper seal. Recommended clamp size is 25-40mm

**** DOES NOT INCLUDE HARDWARE ****** Hardware - ES4772301 The N55 engine is no stranger to oil cooling problems, that�s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned. The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat Features Include: 20�C/68F Lower Than Stock Rock Solid Housing - CNC machined housing. Real Thermostat - Equipped with a real thermostat, not an always open solution. For use in hot and cold climates Quick Installation - Takes only 30 minutes to install.

When it comes to your temperature gauge on your instrument cluster your thermostat plays a large role in where that temperature needle ends up. There are many cases where the vehicle will run a bit cool according to that gauge, oftentimes meaning the thermostat has failed and is stuck open allowing coolant to continuously circulate. The other more damaging side is when it closes shut and keeps the engine from cooling down properly. All vehicles are designed to operate in an ideal temperature range for the ultimate efficiency, life, and performance.
