Expert's advice:
The Mosselman Twin Oil Cooler Extension Kit for the BMW 3-Series (E9x) adds an additional cooler on the left side of the car, allowing you to upgrade a Mosselman single cooler setup to a twin cooler system. It comes with a Setrab 19-row cooler, a pre-assembled bracket, mounting hardware, and a hose kit. The twin cooler configuration is recommended for vehicles operating in very hot climates or for cars that are frequently used on the track.
The twin oil cooler extension kit is an add-on product and requires the Mosselman Single Oil Cooler Kit to function. This kit is not “plug-and-play.” Some modifications to the car are necessary to accommodate the larger oil cooler and bracket. Additional OEM parts required for installation include: the left front oil cooler air duct, left wheel arch air duct, and the inner wheel arch for the auxiliary cooler (left side).
