Oil Cooler

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

The N54/N55 are the powerhouses of BMW, one of the most common tuning platforms, and a fan favorite for spirited driving. Being an N54/N55 owner you know that oil temps can get out of hand leaving you with an anxious feeling and the needle a little too close to the red on your gauge cluster. What if you could get the oil flowing faster, maintain lower temperatures, and still have proper engine warm-up?

Upgrade your N54/N55 engine with our Billet oil cooler housing, replacing the underperforming factory-cast aluminum unit. Engineered for enhanced performance and a blended aesthetic, our Turner oil cooler housing features an OEM+ black anodized finish and our own engineered lower-temperature thermostat. Unlike makeshift solutions like thermostat bypass kits, our housing integrates an OE thermostat, ensuring a gradual yet expedited engine warm-up process, similar to factory settings but faster.

Out goes the factory 110-degree Celsius (230F) thermostat, replaced by our 70-degree Celsius (158F) counterpart. This new thermostat triggers oil flow a significant 72 degrees Fahrenheit earlier than the factory version. This early flow translates into prolonged lower oil temperatures for both the oil cooler and engine, maintaining a happier, healthier engine with consistently lower operating temperatures.

For N54 owners seeking to use the full potential of their tuned or modified engines, our upgraded housing and thermostat are must-have additions, especially for those who frequent the track or enjoy spirited drives on winding roads. Even if you're not pushing your motor to its limits, this upgrade significantly enhances reliability. With rising oil temperatures, the risk of oil breakdown rises, resulting in compromised lubrication, more engine deposits, and increased wear over time. Our solution addresses these concerns, protecting your engine's longevity and performance, regardless of your driving style.

For vehicles equipped with the factory oil cooler, our housing offers a multitude of advantages and is a direct replacement for the OEM unit. If your vehicle lacks a factory oil cooler, this presents an ideal chance to upgrade your setup with our housing, enabling the addition of a factory cooler for enhanced performance and increased reliability. Our primary objective is to maintain optimal oil temperatures, ensuring proper lubrication for the engine's internal components, in turn prolonging their lifespan.

Features:

Thermostat - 40 degrees Celsius/ 72 degrees Fahrenheit lower than the factory unit Billet aluminum to replace the raw cast aluminum factory housing Optional cooler capability for cars without an OEM oil cooler Utilizes the lower temp thermostat to circulate oil sooner rather than an always open solution which inhibits warm-up Combine with OEM oil cooler to add cooling capacity to your FBO N54/N55 or replace the stock housing for a cooling upgrade using your existing cooler Replaceable thermostat and gaskets for easy maintenance Quick easy installation Kit Contents:

Keep your 2021+ BMW M3/M4 cool and collected with the Mishimoto 2021+ BMW M3/M4 performance oil cooler. Much like their predecessors, the G8X M3 and M4 were designed with efficiency in mind. This can be a double-edged sword, as the optimally arranged engine bay has components placed in precarious positions. Most notably, the oil cooler is placed on the undercarriage, parallel to the road's surface. This placement increases air flow and uses aerodynamics to pull air through the core, but it also makes the stock cooler vulnerable to scrapes, bumps, and other road hazards. With this in mind, the engineers at Mishimoto set out to design a robust G8X oil cooler to keep your M3 or M4 running cool on and off the track. We started by swapping the stock tube-and-fin cooler for a bar-and-plate with CNC-machined end tanks. Our cooler boasts a 35.7-percent thicker core and a 41-percent increase in core volume for superior cooling efficiency. Our cooler fits directly in place of the stock unit and retains the stock seals and bash guards for optimal airflow and additional protection. The Mishimoto performance oil cooler for the 2021+ BMW G8X M3/M4 includes everything needed for installation and, as with all Mishimoto products, it's protected by the Mishimoto Lifetime Warranty for a lifetime of protection and cooling. Product Features: Direct fit for the 2021+ BMW G8X M3/M4 Full aluminum TIG-welded construction 41-percent increase in core volume and 35.7-percent thicker core than stock for improved cooling efficiency Robust bar-and-plate core provides superior pressure tolerance and durability Retains stock seals for optimal air flow from fresh air ducts Retains bash guards to protect cooler from bumps and curbs Silver powder coated finish for maximum corrosion resistance No cutting or modifications required Includes everything needed for installation Mishimoto Lifetime Warranty
