Oil Thermostat Racing Valve for BMW 335i, 135i, N54, S55, N55

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.
