Add some much-needed durability and cooling power to your M3 or M4 with the Mishimoto 2015-2020 BMW M3/M4 Oil Cooler kit. True to form, the BMW engineers designed the M3/M4’s oil cooler with efficient space use in mind. Suspended perpendicular from the rest of the cooling stack, this location utilizes the Bimmer’s aerodynamics in order to cool the oil, all while putting the lightweight, tube-and-fin cooler in harm’s way of road hazards.

We here at Mishimoto made sure to beef up the entire oil cooling system design for the F80/82 with our performance oil cooler. We ditched the lightweight design for a full aluminum, TIG-welded bar-and-plate cooler for added strength and cooling. The bars and plates are a much more robust form of heat exchanger core construction intended for improved heat transfer and have the strength to shrug off potential road debris, keeping your oil temps down and where it should be. We also added 10mm to the core’s thickness, equating in a 46% increase in core volume, and increased the oil capacity by .4 qt.

In addition we wanted to add an extra degree of protection to the system by improving on the lines. From the factory, these vehicles are equipped with unforgiving hardlines that are prone to abrasion and corrosion damage. Our oil cooler kit provides a pair of application-specific, flexible, and robust nylon braided lines for a more secure channel for your M’s oil. Also included are our specially designed adaptors allowing for AN fittings from the S55’s oil pump and a secure connection to the oil cooler.

The Mishimoto 2015-2020 BMW M3/M4 Oil Cooler Kit fits directly in place of the stock unit, and includes the Mishimoto Lifetime Warranty for a simplified and worry-free installation.

PROTECTING PERFECTION DIRECT-FIT OIL COOLER R&D CONCEPT, DESIGN, AND PRODUCTION SAMPLE

Oil is the lifeblood of any vehicle. Its lubrication properties keep all the metal bits inside of the engine from shredding each other to dust. While the M3 and M4 rise above just about every other run-of-the-mill commuter car, nothing knocks them down a few pegs quite like overheated oil or oil that finds its way out of the system.External air-to-air oil coolers are typically seen on the sportier variants of any car, but we tend to find a lightweight, tube-and-fin construction. These are cheap and easy to produce but are often better suited for daily driving or maybe the occasional spirited rip down some back roads. They also tend to be more susceptible to damage.

The M3 is all about balance, as we went over in our intro post. For that reason, the engineers at BMW incorporated their own thermostaticoil cooler systemon the front of the M3. The idea is to keep the oil at the optimal temperature during a commute to work, or if you decide to drive past the office and directly to the track instead. However, given the mounting location of the F80/F82s factory air-to-air oil cooler, keeping oil in the system poses a slight challenge for some. These Ms are delivered from the factory with a much sleeker and more aggressive look, and being that these are German vehicles were talking about here, that mean mug has a function. One purpose is to grant more airflow to the plethora of coolers stacked in the front of the vehicle. The other is for additional aerodynamics to boost efficiency and keep the car planted.

In true BMW fashion, there is an exceedingly efficient use of space with regards to the M3s oil cooler. It mounts horizontally along the bottom of the car, perpendicular to the rest of the cooling stack. The graphic above demonstrates the means in which this cooler receives airflow. Essentially, the undertray creates a low-pressure zone behind the underside of the cooler. Basic laws of physics determine that high pressure wants to move to zones of low pressure, which draws some of the airflow from the front of the car. The downside to this methodparking barriers.

The low-slung sports sedan (or coupe) is at an increased risk of gashing the factory cooler on any sort of raised road hazard, especially once the car is lowered even more, like ours. So, you really have two options. Either go full baja M3, or add some heft to your oil cooler. We here at Mishimoto have already started on the strength option.

The core isnt the only thing getting a new suit of armor. To make sure that every part of the oil cooler is protected, Dan also made some updates to the coolers end tanks. Instead of thinly walled tubing, the end tanks on our design are billet aluminum and TIG-welded to the core for a secure connection to the oil system.

Our updates in durability come with the added benefit of cooling capacity as well. Since we based our new design on BMWs, we still incorporated a large fin surface area, but now combined with a 39mm core thickness, the core size is increased by 46%. Combined with the robust bar-and-plate core and increased oil capacity, we expect to see more manageable engine oil temperatures, especially on the track.

Whether its keeping it cool or keeping it in the car, protecting your oil is key for the sports sedan benchmark. While the S55 is a dynamo of both power and efficiency, that all starts to crumble once the stock cooler soaks with heat or gets lacerated. Our new design has a cool head under a suit of armor that keeps your M-powered sedan doing what it was designed to do.
