Worth the investment! Only downside is the longer wait time for oil to get up to temp, especially with aftermarket intercooler.

I never really noticed a difference with oil warm up times and I have an aftermarket intercooler. Definitely worth $60!

Excuse my noobness, but what does this cooler valve do? Just cools the oil?

I've noticed in hot cali days with 100F, my car's oil has been running close to about 250F, which worries me a bit although the manual states anything <300F is normal. Not freaking out about the oil temps but lower is always better right?

And how exactly does it do it with a simple part like that?

It blocks the oil cooler bypass so that ALL oil will now go through the cooler instead of being temperature dependent.

Exactly. The oil cooler is not enabled until the oil reaches a certain temperature. Don't quote me on this but I think its about 245 ( i'll let the experts chime in on this). This bypass will enable the oil cooler to constantly run / work lowering the oil temps as long as the car is on.

Colder oil is not always better, but the BMS bypass safely lowers oil anywhere from 30-10 degrees, at least in my experience. ( have installed it and observed it in three different n54's )

Overall worth it IMHO

Correct, this is only for cars equipped with factory oil coolers. You can always retrofit one, but I wouldn't only consider this if I found a really good deal on one. Many upgraded their oem oil cooler to an aftermarket one.

For future reference for CA guys, you must email us first before ordering otherwise the order will be flagged since it is not CARB legal. Some items may not be in stock so it will require a 5 day lead time before it ships out to you as it has to come to our facility first.

Just flip your thermostat and save $60. Free upgrade and it does the same exact thing.
My temps stay in the 215-220* all day in fl 90*+ weather

I'm assuming you did what this guy did,
. Did you replace the first two bolts that he removed?

you dont deal with leaking oil for reusing the alumium bolts ? (namely the two that were removed first in the referenced youtube video)

Just want to be sure becuz i've heard some people having that problem...

I've yet to do this but am circling this mod like a vulture. I just want to understand the reasoning behind the BMW oil temp specs and if there are down sides if any at all to running 20ish degrees below the normal 240.

I have noticed my car seems quicker at lower temps (or at least in my rumpDyno).

Anyone have info on this or links?

I didn't have any leaks, but I also used rtv gasket maker ( very very little) to assure no leaks.
Reusing aluminum bolts are perfectly ok it's the bolts with blue paint you are suppose to replace. The reason I used rtv was because of the gasket there. I have been running this for months and it's bone dry! Car doesn't see temps above 230* in fl 95* weather. 99% of the time the car runs about 215-220*
