The stock thermostat is designed to open at 97C. This leaves your engine running fairly hot, and running for quite awhile before your thermostat will begin operation. With the Mishimoto Racing thermostat, the activation temperature becomes 74C. That's 23C cooler, meaning you can rest easy knowing your engine will stay cooler to help avoid all the problems that can be associated with an engine running hot. The water pumps in these BMW models are known for failure near 80,000 miles is a very common issue often times leaving the owner stranded. This kit provides a single stop for water pump and thermostat replacement needs to save the search and get you back on the road.

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

When it comes to cooling system hose replacement, the "U" shaped hose connecting the water pump to the thermostat is usually the first to fail. A lot of this comes from its close proximity to the hot downpipes, while some of this failure comes from the sharp bends in the hose. 

Why not upgrade when you're due for a replacement? The ECS Tuning silicone hose replacement fixes these issue with two key features in their design. Offering this hose in a much more heat resistant silicone instead of OE rubber and having the hose wrapped in aluminum. The aluminum coating acts as a heat shield to further protect the silicone as well as reducing the temperatures forced on the coolant running through the hose.

The N54 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.
