Colder air is denser and therefore has a slightly higer oxygen content. It is usually also less humid as well, again dry air tends to be slightly higher in oxygen content.

Additionally the colder air temps also keep the air intake path a bit cooler, for better overall performance.

What you are experiening is fairly typical as air temps drop close to freezing.

svck on that non 93 having californians... Snowpocalypse = Mpocalypse :M5launch:

Tortuga is this the one you added?
Products - Pro-Line Eingine Flush

based on the instrucitons it seems like it's just ATF fluid...

p.s. in the video the sludge looks like it was brushed on and nothing is coming out of the bottle...commercial trickery or

maybe i'll try it at 100k miles or if i find too much sludge in the oil pan

Try driving a turbo or super charged car in 35 degree weather as compared to 95 degree weather, entirely different car!!

Tortuga,

So funny you mentioned this. I noticed yesterday that when I drove my car and got on it through 3rd gear, the red light flashed on my boost gauge. It is set at 9psi. That was in 42 degree weather, the most boost I have experienced yet. Car continues to pull like a freight train. Even though its not news to me, it is still amazing how much of a difference the cold/dry air can make.

Winternationals are in Pomona today, I would venture that records will be broken.

cold temps do boost performance... on the other hand, when it's too cold, m5s are more likely to throw 2ndary air filter codes, exhibit creaky steering, squirrel around in the snow/ice, etc. I'm jealous of Cali's climate-- sometimes cold enough to get the good side, but generally, not too cold to induce the drawbacks.

So this is what it feels to be you guys

It's a tradeoff. When it's really cold it's very nice and peppy but with snow tires, grip isn't that great when cornering. But on the highway, it's very nice.

Colder weather does boost performance to a point. When you get under freezing it starts taking it away as the air is dryer.

Anybody else used that engine flush
