Product Information
THE ULTIMATE COOLING SOLUTION FOR THE F-SERIES N55 ENGINE
Push your N55 powered F2x, F3x hard enough at the track and you'll know all too well about the buzz-killing oil temperature limp mode. The stock engine oil cooler is not sufficient at the track - temperatures skyrocket, oil deteriorates and limp mode is entered. Once limp-mode is entered you need to reduce the load on the engine to lower the oil temps.
With the CSF Race-Spec oil cooler say goodbye to nursing your car around hot oil temps! The cooler, tested in excruciating 46C temperatures, has been proven to lower your BMW out of the oil temp limp mode and bring the fun back!

Mounting process could have been easier but still a beautiful cabinet
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Beautiful cabinet seems to be good quality I just keep admiring something so beautiful about the white. The extra hardware is thoughtful.
With some master skills I was able to get it mounted perfect. It was not a breeze but nonetheless I always find a way.
I found the best way to mount this was to hold it against the wall and follow the pre-drilled holes at the bottom to drill the holes into the wall that wasnt that hard
But for the top anchor/screws, the cabinet did not have pre-drilled holes and I was not about to guess !! So I used alien tape to tape the top wood bar to the unit as shown in pic then took the cabinet lined up the bottom holes while holding the cabinet up then I drilled holes through the unit with a small bit just to get the whole going then took it back down then followed the same holes with a bigger bit and it worked for me. It hung level.
It was crazy that the pre-holes were not 16” apart when they could have been. I added extra screws to be able to mount them to a stud I didn’t feel comfortable with it not being mounted to a stud. The screws I had were too long gonna have to get some shorter screws. But it’s up & looks so nice
DO NOT USE 11/32 bit. Don’t even use 5/16. I use 1/4 and kinda ran the drill in a circle to widen the whole and it was the perfect tight fit
All in all I do love the cabinet. Just feel the mounting process could have been instructed more conveniently

Love it !!!!
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
I absolutely love this cabinet. It’s super well-made easy to put together and the space is great. I’ve already received some compliments. Thought it would guests. Come to my home. Just look at how nice it pairs with my bathroom. The handles are sturdy. There’s also a nice tag inside with the company’s name. If you’re looking for a bathroom cabinet, highly recommended this one is well worth it. Love it!!!

Excellent Cabinet for someone good at mounting a cabinet
Color: White, Style: Wall Cabinet
The cabinet arrived very well packaged with an instruction booklet, hardware, and an Allen wrench. The booklet says you will just need a Phillips screwdriver, but you will also need a drill with an appropriate bit (more on the bit later) to mount the cabinet on the wall.
Assembling the cabinet was simplified by how well the cabinet pieces and hardware were labeled and referenced in the instruction booklet. The holes in all the cabinet parts lined up nicely.
The doors swing on spring loaded pivots. They are not adjustable, but work well and are probably much less expensive than European style hinges. I was concerned that the doors would not line up, but they look fine.
The Magnetic Latch also works well, but the little piece of wood that it mounts on fell off during assembly so I glued it back in place. This was the only problem I had assembling the cabinet. I let the glue dry overnight and mounted the cabinet the next day.
The wood support plate they ship with the cabinet is a great way to hang a cabinet, however I did have some problems using the supplied anchors. I recommend having some other anchors and screws available in case you have similar issues.
Skip this paragraph if you do not care about the details: I mounted the cabinet on drywall. The instructions said to drill 11/32” holes for the supplied plastic wall anchors. I did not have an 11/32” bit so I used a 5/16” bit. Even though my holes were 1/32” smaller than specified, the anchors slid into the drywall very easily without having to tap them. I recommend using a 5/16” bit or even a 9/32” bit instead of the 11/32” they specify. Next I mounted the support plate with the supplied screws, but I could not get the screws tight enough to hold the plate securely in place. It felt like the screws were too small in diameter so I used some slightly larger screws. That worked fine for one of the screws holding the plate and the two lower screws, but the second screw through the plate would not bite and hold the plate firmly. Fortunately I had one HILTI 3/16” hollow wall metal anchor left over from a previous project and was able to get the plate very solidly attached to the wall.
My wife is very pleased with the cabinet. I did have some trouble with the latch and the install so I was tempted to knock off a star, but I think this is a 5-Star item considering the low cost and how well the the cabinet parts aligned with each other.

Love and amazing for the price!
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Perfect! I'm a renter and didn't want to spend an arm and a leg on something that might not work in the next place so this looked like it would be a good fit. I really wasn't expecting much for the price point but I was VERY pleasantly surprised. It's a great piece.
I love assembling things (I'm an Ikea pro) but this had literally the easiest and most explicit instructions I have ever seen. Every piece is clearly labeled. The hardware comes in a bubble pack, again clearly labeled. Rhe instructions are very clear.
Another thing I appreciated was the mounting mechanism which is a French cleat. It is much easier to level and screw in a cleat than to recruit help and try to hold a cabinet in place and try screwing it in. I'm a fat middle age woman and I had no problem mounting it by myself.
Notice there are no screws visible on the outside. That was a huge selling point for me.
Only con is that for the quality of everything else, the shelves are on the thin side, placing anything substantial would definitely make them bow.
Background is a scrap of peel-and-stick.

Good cabinet choice
Color: White, Style: Wall Cabinet
I needed a wall cabinet for a recessed area above the toilet. This one fits the area perfectly and provides a good amount of storage in an otherwise wasted space. It looks good as it coordinates well with my white shaker style cabinets elsewhere in the room. It was easy to assemble, doors lined up perfectly, and mounting was a breeze with the included screws and hardware. It doesn't get hard use in this location, but seems sturdy after almost a year.
