Product Description
Our Differential Fluid Cooler is effective insurance that will help preserve the high-performance clutch discs in your E30, E36, E46, E9X limited-slip differential, increasing the longevity and maintaining performance under pressure.During a track session, differential fluid temperatures over 280°F are not uncommon. A limited-slip diff that starts at 40% locking will wear much more quickly under these conditions. This kit is the most effective way to lower differential temperatures to extend the life of your limited-slip clutches and general wear parts. This can be combined with a finned diff cover on E30, E36, and E46 to lower temperatures even further. However, this kit is efficient enough to work with non-finned covers, which is our preference for a car that will be driven aggressively over curbs.
Our kit includes heavy-duty fluid pump with Buna rubber seals, Setrab heat exchanger with an efficient, integrated puller fan and shroud, and all -6 stainless line, hose ends, bulkhead fittings, and adaptors for a clean installation in your spare tire well. This system increases oil capacity by just under one quart.
Assembly Note: because not all race cars are the same, the hoses do not come pre-assembled. The included fittings should allow for flexibility in fitment. As with many race car applications, some mounting fabrication and creativity may be necessary, depending on your setup.
Fitment Note: Many 2006+ non-M models only have a fill plug and do not have a drain plug in the differential. In these cases, a M22x1.5 bung must be welded in place. If you are buying one of our performance differentials, contact us about having this done for you.
Popular applications include E30, E36, E36 M3, E46, E46 M3, E9X 335i, and E9X M3 race, track, or drift cars.
