CSF Radiators Race-Spec Dual-Pass Oil Cooler for BMW E46 M3/E39 M5, Aluminum, Motorsport Silver Finish
$549.00
Free Shipping Hurry Low Stock
If you’ve ever taken your E46 M3 or E39 M5 out for a spin on the track, you know that the factory oil cooler just doesn’t cut it. After a few hot laps, those oil temps can skyrocket, and that’s a one-way ticket to engine trouble. That’s where the CSF x Rogue Engineering oil cooler comes in—designed specifically for those of us who really push our cars to the limit. This isn’t just a slight upgrade; it’s a serious piece of kit. The new cooler is over twice the size of the stock unit—243 cubic inches compared to the factory’s measly 103 cubic inches. That means you can count on cooler oil temps even on the hottest days when you’re really hammering down the straights. The construction is another level up. With a Bar & Plate design instead of the typical tube and fin, this cooler is built to take a beating. You won’t have to worry about debris from the road or track damaging it. Plus, the extruded end tanks are way tougher than the flimsy bent aluminum you find on the OEM cooler. Installation? It’s a breeze. It bolts right onto your factory radiator or you can pair it with CSF’s High-Performance Radiators (like the CSF #7058 for the E46 M3 or #7064 for the E39 M5). You can use your existing oil cooler lines, so you’re not left scrambling for extra parts. Here’s the nitty-gritty: this cooler has a unique top/bottom dual-pass design that maximizes surface area and flow, ensuring your oil stays at optimal temperatures. With eight rows of cooling power and a high-density multi-louvered fin pitch, you’re looking at one of the most reliable and durable oil coolers out there. And it fits perfectly with your OEM bumper, so if you’ve got an aftermarket splitter, you won’t run into any clearance issues. It’s finished in a slick motorsport silver that looks as good as it performs. So, if you’re serious about keeping your engine happy while you’re out there tearing up the track or the streets, this oil cooler is a no-brainer. It’s been designed and track-tested by the folks at Rogue Engineering, who know a thing or two about BMW performance.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.
