Precise Oil Temperature Control for Your BMW

Upgrade your BMW N20, N26, N51, N52, N53, N54, N55, and S55 engine's oil temperature control with Improved Racing's high-performance oil cooler adapter.

Designed to address flaws in the factory's restrictive oil cooler adapter and faulty internal flow control valve, this upgrade ensures precise oil temperature control.

Improved Racing's thermostat provides quick engine warmup, prevents overcooling, and delivers full oil cooling capacity on demand. Trusted by professional race teams around the globe, Improved Racing's thermostats have proven highly reliable, are backed by a lifetime manufacturers warranty, and are made in the USA.

Option to Use the Factory Oil Cooler and Lines

The optional factory oil line adapter allows you to use the factory oil cooler lines for a simple, plug-and-play installation. For maximum performance, the factory oil cooler and lines may be replaced with an aftermarket cooler and AN lines using the AN adapter fittings (-10AN line size is recommended).


Please note that some applications, such as most BMW SUV's, use a water-to-oil heat exchangers. These applications require plugging the coolant supply and return ports, as well as adding an external air-to-oil cooler and lines (factory or aftermarket). Please note the EBW-100 adapter cannot be used without an oil cooler.

Vehicle Fitment

Designed for a direct fit to any BMW engine equipped with oil filter housing part number 11428683206 or 11428642289 (circled in blue in the diagram below). The application is extremely large and covers most BMW cars and SUV's across all series!

You may view our complete application list, including chassis and engine code, in the EBW-100 Complete Application Reference file found in the documentation section at the bottom of this page.

Compatible with all applications equipped with the following BMW engines:

  • BMW N20 engines
  • BMW N26 engines
  • BMW N51 engines
  • BMW N52 engines
  • BMW N53 engines
  • BMW N54 engines
  • BMW N55 engines
  • BMW S55 engines

Determining Your Application

Some applications require adding an external oil cooler. To determine your specific application, refer to the diagram below.

  1. Direct-fit applications (green circle): If your vehicle is equipped with the oil cooler manifold circled in green, you can replace it with the EBW-100 and sometimes use the optional factory line adapter to retain the factory oil cooler (see additional notes on variants below). You may also replace your oil cooler and/or lines with aftermarket AN lines to improve performance with any of the three variants below.
    1. Variants: There are three variants of the factory thermostat housing:
      1. The first variant has factory lines exiting the bottom of the factory housing, and uses an M8 screw inserted from the bottom. The EBW-100 is a direct bolt on for this application using the factory lines with the optional factory oil line adapter (EBW-100-98).
      2. The second common variant has factory lines exiting the bottom, but uses an M6 screw that is inserted from the top to retain the factory lines. To use the factory lines on this variant, the M6 hole in the center of the factory line flange must be drilled out to clear the provided M8 screw. If using aftermaket lines, the EBW-100 will work without any modifications.
      3. The third common variant has factory lines exiting the top of the factory housing. The EBW-100 cannot be used with factory lines in this case. You must use aftermarket AN lines. Improved Racing is developing a new adapter for this application, which will be available soon.

  2. Applications requiring the addition of an oil cooler (red circle): If your vehicle is equipped with the water-to-oil cool circled in red, you will need to perform these additional modifications:
    1. Cap off the coolant feed and return ports at the source.
    2. Install an OEM BMW air-to-oil cooler and lines, or install an aftermarket air-to-oil cooler and aftermarket AN lines.
      Warning: A cooler must always be equipped. Do not cap off the inlet and outlet ports of the EBW-100. This will result in the complete blockage of oil flow to your engine!

Very sharp exposed corner! Easy to cut yourself.
Overall, this does exactly what I need it to but there is a sharp exposed corner that makes this a little difficult to use. One wrong swipe and I cut my face. If they rounded that corner off, it would be perfect. Just be very careful!

Does exactly what it says!
Let me preface this review by saying I am not a trend follower. Truth be told, I only watch animals in FB and Tiktok videos. That being said, I'm 43 and have hair growing on my face like I was dipped in a vat of testosterone. No lie - I look in the mirror and see the wires on my face trying to grow together to form a connection. As electric of a personality I am, it's no bueno for self esteem. I'd heard of dermaplaning, and have seen my friend use the razors with zero fear. She's whipping it around like it's a wand of wonder, and she looks and feels fantastic afterwards (yes, I grabbed her face to feel the difference - boundaries, I know). The one she buys is different than this one, and much more expensive. My maiden voyage was totally my fault. I had two too many glasses of fun juice and way too much confidence to weild a blade. I ended up with one shorter eyebrow and a couple of cheek slices that required a little more than light compression. Luckily, I was going to a rock concert the next day, so I couldn't have planned the snafu at a better time. When I tried again, with zero caffeine and hydrated to the max, it was an absolutely amazing result. I used a thin layer of coconut oil because I didn't have aloe (reviews). Not only did everything get smooth (seriously couldn't stop touching myself), but I realized I should use coconut oil more often. I even think after some practice I won't be afraid to cut my jugular because I hiccup or sneeze. This product is 100% worth the low price, just as long as you're sober, experienced, or willing to bleed out.

Removing Peach-Fuzz from your face :)
Before I ordered this item I did not know how important it would be to remove peach puzz from my face. By removing the tiny peach fuzz from my face, I am creating the smoothest possible surface for my skin, and for my makeup. I never truly understood this until I tried this method & saw the amazing results. (Being vision impaired, I also never really saw how much peach fuzz a normal human being has... until I used this item.) I highly recommend this item for anyone who wants to take care of their complexion and how their makeup and skin looks on a daily basis. I still can't believe it, but it's a real game changer! (Oh & by the way, these things fold in half, so the blade is covered and it can be carried in your makeup purse without any danger to you.) Enjoy!! 💖 XO

Cut my face
I’ve tried several brands of derma blades in recent years. This is the first one that cut my face in several places. It definitely thoroughly removed facial hair and exfoliated well but be careful. It also felt a little cheap and too lightweight which made it difficult to maneuver.
