Alright, fellow gearheads, let me lay down the
facts about the MaLo Industries oil thermostat racing valve. We put this bad
boy through its paces on the track, in bumper-to-bumper traffic, and even
during that scorching 2021 heatwave when temperatures hit a blistering 115°F
(47°C). And you know what? It barely broke a sweat, with oil temps hovering
around a cool 240°F (115°C), all while rocking the stock oil cooler.

What's the secret sauce, you ask? It's the MaLo Racing Valve's
knack for maintaining a steady flow of oil to your heat exchanger, ensuring
your engine stays cooler than a polar bear's toenails. And let me tell ya, this
baby's been machined to perfection, with tight tolerances that scream maximum
performance. Plus, forget about fussing with springs—ain't none of that here.

Oh, and did I mention it comes with a sweet little bonus? You'll
get yourself a thermostat replacement O-ring thrown in for good measure. And
hey, if you're the kind who likes to have extras on hand (I mean, who
doesn't?), make sure to check out our thermostat lid replacement seal.

Just one thing to note: you're gonna need an external engine oil
cooler, but don't sweat it—standard on most models from 2008 onwards. So go
ahead, give your ride the upgrade it deserves with the MaLo Racing Valve. Trust
me, your engine will thank you later.

How it all started

In 2019, fueled by a love for high-performance vehicles, I embarked on a mission to upgrade my N54-powered 135i with a single turbo. In the process of addressing all known issues on the N54 I learned about the serpentine belt problem and to my surprise found no viable solution on the market.
As CNC Machinist by trade, I decided to take matters into my own hands and thus MaLo Industries was born.
