Oil Coolers

The original OE oil cooler from BMW is an all metal design which would make you think it would be fairly robust. However, there are several weak spots in the design that tend to cause leaks. The CSF Race-Spec design reinforces the weak points, especially around the feed and return lines. CSF’s solid line connection block can handle any abuse thrown at it while the reinforced and braced return tube is rock solid. CSF also upgraded the more fragile Tub/Fin core to a robust and durable Bar/Plate design. The core is 40% larger than the factory unit with 2 additional rows of oil cooling and much thicker core (63mm vs OE 45mm). This offers superior cooling capacity and volume for the oil system. TIG welded end tanks round out the slew of upgrades creating a much stronger connection than the factory brazed construction.

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 engineers over at CSF know cooling. So when it comes to keeping your engine oil temps down as you push your E9X M3 hard on the street or track, a CSF Oil Cooler is the obvious choice. Engine oil temperatures are a big concern to anyone who tracks their vehicle or pushes it hard on hot days. High oil temperatures in modern cars will send you into “Limp Mode” in order to protect the engine but slows you down to a crawl and is overall an unpleasant experience. Old vehicles without these safeties built in can experience major engine damage if oil temperatures get too high. In any case, overheating engine oil is a bad thing, so why not do the most you can to keep them in check and don’t let something like this spoil you fun or ruin your vehicle.

While mounting an additional cooler behind the grill is the simple option, that just adds more heat to the full system and takes away from the cooling capacity of the radiator. On top of that, most owners who track their cars will have an upgraded/larger intercooler which further compounds the issue. That means the sides of the bumper are the obvious and optimal placement. However, the FL5 does not have great airflow in that area. To improve airflow, CSF needed to design a ducting/inlet system that would allow proper airflow for optimal performance.
The engineering team set out to develop CSF’s first ever complete engine oil cooler kit, and the results speak for themselves. CSF’s new engine oil cooler kit is the “Real Deal” with stunning performance and an aggressive look to match.

One of the goals of the CSF 911/930 Engine Oil Cooler was to have a single unit that could fit both older (65-71) and newer models (72-89). The solution may seem simple, but engineering the two upgraded stainless steel fittings so there was no oil flow restriction took some extra design work. CSF took some inspiration from the CSF 911/930 Turbo Fender Oil Cooler (CSF #8168) using a similarly designed “Widemouth Fitting”. The threaded M30 “Widemouth Fitting” for the 65-71 models maintains the optimized inner diameter (ID) of the oil pipe to maximize flow through the oil system. The “Widemouth Fitting” offers 50% greater flow capacity over the OEM connection. The machined in-house Stainless Steel fittings offer increased strength and durability over the OEM Aluminum slip-on tube (72-89 models) and threaded M30 fitting (65-71 models). Both OEM connections are common sources of leaks. CSF also includes two high quality copper crush washers to offer the best possible seal and prevent any leaks.
