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. "

    Stylish Aesthetic with Functional Limitations
    Color: Black
    This desk organizer offers a sophisticated look that complements modern furniture and decor quite well. The combination of aluminum and walnut creates a professional appearance that effectively tidies up a workspace or nightstand. I particularly appreciate the soft-touch base, which provides a safe surface for delicate items like phone screens or watches, ensuring they remain free of scratches. Additionally, the materials are very easy to wipe down and maintain. However, the build quality does not entirely justify the premium price point. The aluminum components feel more like thin, shaped sheet metal rather than a solid, high-end material. While the walnut accents are a nice touch, they lack the weight and substance I expected for a valet tray in this category. The primary functional drawback lies in the magnetic adjustment system. The magnets are relatively weak, meaning that accidentally bumping a divider while reaching for an item can easily shift the layout. This requires frequent readjustments, which can be frustrating during a busy workday. Furthermore, the magnetic rails can interfere with other metallic or magnetic objects you might try to store. If you are looking for a purely aesthetic upgrade to organize lightweight items, this tray serves that purpose, but it falls short in terms of stability and material density.

    Love the customizable dividers
    Color: Black, Color: Black
    I really like this desk drawer organizer tray. It comes with two removable adjustable dividers that are magnetic. They have a strong magnetic pull and stay in place and do not move or shift at all. I love the overall look of it. It’s very sophisticated looking. It can be suitable for a man or a woman. If it’s into my drawer perfectly and I love the smooth modern design of it.

    A nice customizable organizer.
    Color: Black, Color: Black
    This is a nice organizer for a drawer or nightstand. Comes in a box that is not overly bulky and is well protected. It's quick and easy to adjust and put together. the seperators are magnetic so you can customize it to fit your needs. There are two cut outs for charging cords and it fits a phone easily along with other accessories. The unit feels solid and well built, it has a good weight to it. I do wish the deviders were a bit easier to get square, but that's more just my idiosyncrasies.

    Nice Desk Organizer
    Color: Black, Color: Black
    This particular desk organizer has the little strips of wood that each have a magnet installed inside them. This allows you to move the wood strips to different locations and adjust the areas to fit whatever size item you want to put in there. It's very easy to just move them around and the bottom of the tray has a nice material in it that prevents scratching the items you place in there. The usable area on the tray is 12-1/2" x 8-1/4" x 3/4" and the overall size is 13-5/8" x 8-3/8" x 1". It fits nicely in drawers or simply having it sit on top of a desk to hold items. It also is made out of good quality and is very sturdy.

    Great product quality
    Color: Black
    This had literally everything I was looking for, but… just too large for the area I wanted it in. Check the measurements and compare that to your actual space. If they had about 1/2 to 1/3 of this size I would snatch it up in a heartbeat. It has a groove for your phone charging cable and the moving magnetic dividers are genius. I’m looking for something to put on my nightstand to allow the phone to charge at night but face down. Extra section for earrings or hair accessories, etc would be great. This has that potential. Just needed it smaller.
