EXPERT'S ADVICE
"Upgrade the Single Oil Cooler Kit of your BMW 1-Series E8x to a Twin cooler setup with this Twin Cooler Extention Kit E8x. The twin setup is recommended for cars in a very warm climate and cars that will be used on a track.
The Twin Extension kit comes with the 1x Setrab 19 row oil cooler, 1x stainless MSL bracket, 1x Mounting bracket, and a hose kit (1 oil hose).
Note: This item is not ''plug-and-play''. You will need to make some adjustments to the car to fit the bigger oil cooler and bracket. Additional OEM products that you need for the installation are: oil cooler front air duct (left), wheel arch air duct (left), inside wheel arch for the auxiliary cooler (left).
Installing the twin oil cooler extension on a BMW 1M requires some extra modifications to make the left oil cooler fit into the car. The 1M is equipped with an auxiliary water cooler on the left side of the car. This is the place where the second oil cooler needs to be installed. To make this fit the auxiliary watercooler has to be removed and probably a bigger radiator has to be installed. It will add extra time to the installation process. "

Esthetically sound, materially flimsy
Color: Beige, Size: 4 Panel-67”
The item at first seemed okay and quality was good. But it’s a little flimsy and tips over frequently. I’m thinking of returning and replacing pretty soon.

Perfect for working from home, creating privacy in my home office.
Color: Beige, Size: 4 Panel-67”
Easy to put together, took about 10 minutes by myself. I laid it on the ground folded (make sure the same direction for the brackets match). The only issue I had was one screw would simply not go into one side of the connectors. Using it as a background for my home office, so it won’t be moved often, so not super concerned, not enough to take the rest of it apart to see if I could fix the issue. Looks great, creates the privacy I needed for meetings.
