Mishimoto BMW E46 M3 Oil Cooler Kit

The engineers at CSF know cooling. So when it comes to keeping your power steering fluid temps in check as you push your E9X M3 hard on the street or track, the CSF PS Cooler is the obvious choice. While often overlooked, your power steering system can become quite annoying if it overheats. As power steering fluid boils it gets bubbles in the system leading to sloppy steering response and a noisy pump. On top of that, you will need to replace your power steering fluid if you let it overheat which is both annoying and an added cost.
The CSF E9X M3 Power Steering Cooler is approx 40% More Efficient than OEM Cooler. Designed to Work with any Aftermarket Supercharger, Heat Exchanger, or Auxiliary Coolers that may be Placed Underneath OEM-Positioned Power Steering Cooler.
The CSF #8041 Cooling product is designed to be a “Drop-In Fit” application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.

Add some much needed durability and cooling power to your M3 or M4 with the Mishimoto 2015-2020 BMW M3/M4 Performance Oil Cooler. True to form, the engineers at BMW designed the M3/M4’s oil cooler with an efficient use of space 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 light weight, tube-and-fin cooler in harms way of road hazards. We here at Mishimoto made sure to beef up the oil cooler 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-percent increase in core volume and increased the oil capacity by .4 qt. The Mishimoto 2015-2020 BMW M3/M4 Performance Oil Cooler fits directly in place of the stock unit, and includes the Mishimoto Lifetime Warranty for a simplified and worry-free installation.
High-performance engine oil cooler designed to regulate oil temperature and protect critical engine components. Efficient heat dissipation improves durability, maintains lubrication, and ensures reliable performance.
