Engine Bay Layout
Coming from and E36M3 and E46M3, and never having owned an E9X or F3X, I have no experience with FI. Looking at the engine bay of the F8X, what is the plastic box on the 'cylinder' side, sort of behind the headlight, and the one on the 'intercooler' (driver's) side, sort of behind the headlight? I'm just used to the air intake being on the driver's side. Do FI engines have a second air filter?? Once again, I've only ever had NA engines, so please excuse the sillyness of the question. Thanks.
And why is there no dipstick? |

There hasn't been a dipstick on a BMW in years, unfortunately. Gotta trust the computer.
Looking at that picture, the box on the passenger side behind the headlight is one intake box, and the similar-looking box on the driver's side is the other. Each turbo gets its own intake. |

So how do the dealerships do oil changes? They use the actual drain plug and go old school? Figured most dealerships just sucked it out of the dip stick insert. My car didn't come with a dip-stick but you can buy one, remove a plastic cap and install it.

I believe there is a water to air cooler at the front already, but I do not know if it can be replaced with a bigger one. |

The described method is commonly used in boat engine applications since it's difficult to drain the oil below the sump... I also know that many garages prefer the oil pump method as that is a clean and easy way of changing oil. No need to dismantle protective shields and spill oil on the surrounding bodywork/cross members etc.

Sooooo, then, if you wanted to do a pump-type oil change, how would you do it for a car like this?? Also, thanks people for clarifying that the car has 2 air intakes, one on each side. Love the straight six turbo. I see SOME, SLIGHT, MAYBE resemblance to the NA 6's in the E46 and E36 |

I still use the pump for my Honda van, but the BMW's go on the RaceRamps now for oil changes. .

Like I said above, changing via the port is easier and less chance that the 19 year old doing your oil change will strip the drain bolt and cause a leak. Bad because it probably doesn't get out all of the gunk the way a traditional change does. |

Yes, there are water coolers behind the front bumper, and they're all ducted and seem to fit their respective areas nicely. Any water cooler you get would likely only be able to ne bigger in thickness, which would require trimming of the ducting. Doable though! |

Yes there is, that's what that big silver box is on top of the engine. Two pipes on the passenger side go in with hot air, one pipe comes out the driver side with cooler air and goes into the manifold.
It's a water-to-air system, so the water has to be circulated through radiator(s) so the air coming out of the turbos actually cools down before going into the engine. Water cools the hot air coming out of the turbos, and ambient air cools the hot water coming out of that intercooler. That's how the systems in the M5 and M6 work. |

I expect aftermarket vendors to offer CF intakes to replace the plastic ones. Big bucks there. But high scores for the bling factor. Now, I wonder if such a thing will actually help performance?
The lack of a dipstick is major fail for BMW. They forgot it in the E92 M3 and it looks like they forgot it in the new F8x M's too. Cheers.
