Description

The Mishimoto BMW Racing Thermostat fits all N52, N54, and N55 engines. It will promote greater cooling efficiency throughout your engine. Mishimoto racing thermostats will significantly lower high engine temperature produced by modified and upgraded N52, N54 and N55 engines. Once the engine is fully warmed up the Mishimoto Racing Thermostat will open up at a lower temperature than the stock thermostat, allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.

  • Dont Waste Your Time on this Product ; Nightmare to install and no Support
Mishimoto ; is just selling this with no Support ; I spent all day trying to install this and in the process damaged the OE electrical pin on the OE Plastic Housing; it evidently has to come out ; ( Impossible without destroying the Pin and / or Housing) and Reading on Forums a guy got his installed; and Car immediately over-heated; apparently you only want this is you are Tracking the Car only and another guy mentioned you can change coolant temps in Tune ; which makes this a Nightmare of an Install Not worth it. Had to spend $150.00 on a new Thermostat and housing from Advanced Auto or the Car would've sat for 3-4 days waiting on part from FCP Euro Mishimoto has NO Support or Detailed Instructions on how to install this; I was on the phone with them 5x in 6 hours trying to get a clear answer. Horrible Experience ( and I'm one that trys not to Complain about anything) ... show more

  • Faulty and extra labor cost
Received the item in a broken original box. Amazon package itself wasn’t damaged. Installed it in an OEM thermostat plastic thing but I noticed that the water temp was 40C~55C on a freeway. Too low temp. Took my car back to a shop and replaced this Mishimoto thermostat with the OEM one, costing extra $500 for the labor. No joke. Was hoping this item works better than the OEM one temperature wise, but it didn’t and costed me that much to replace it. I won’t buy any item from this brand. Period. ... show more

  • Run Away!
Purchased the Mishimoto E90-07 with the idea that lowering the initial "kick-on" temp. of the cooling system would be a good idea. Reality is the piece of crap does not fit the specified plastic thermostat housing and is different in face diameter and temperature extension. The thing simply is not compatible with my 128i. Looking at 1 Series and E9X 3 Series forums shows many people stating this PoS does not work. It simply is the wrong size for the specified housing. ... show more
