Air intake located lower than other cars?

[Oris318]

Guys,I was told my my mechanic that the air intake thinggy in BMWs is located lower in the engine compartments, compares to other automobiles. I wonder if this is true. This concerns me, especially when we go through water catchments/flash floods during raining season.

u mean the original one?..or your after-market, funky looking KNN filter?.....

theres a tendency to locate it downwards towards the bumper area sometimes, cos theres a nice big space there.. obviously u're right that it might get wet..and therefore ineffective..
most ppl i know just shield off the space where the airbox USED to be, and lcoate their cone filters there...

i dun think the stock airbox is located any lower than any other cars i've seen... in fact, its located further front than my Clio, which has a longer hose plumbing air towards it from the grills..

Standard intakes are located at engine level - like all other cars. I've splashed through some soaking puddles with no adverse effect.

I had my car service at the workshop recently, and then I saw a brand new 530I that need pistons replacement. I was informed that the owner drove through water catchment about 8 inches and the water went into the engine. Apparently, my mechanic told me this is because the air intake is lower than other automobiles. I symphatize the ower, because it costs him around RM28,000 to get his car back in shape.

My boss drive the same model, and he had almost similar problem when drive through flash flood/water catchment area. He saw some smoke coming out from the engine compartment. Luckily he still can drive the car.. ..

Just wanna share these info with you guy...

I tot they were located above and behind the kidney grills? Meant to suck in cool air instead of engine temp air.

i don't think it's wise to drive thru flood water with the newer aluminum alloy engine blocks, doesn't it crack with sudden temperature change. Not sure how well the magnesium alloy block in the even newer valvetronic engines can withstand sudden change of temperature.

agree..absolutely..the air intake is lower and it is suicidal to drive through water duriing flash flood etc..the magnesium alloy engine is totally protected agaist this from happenin..my mechanic once showed me the e60 engine bay and underside of it..totally sealed..he said that the magnesium alloy is even more prone to sudden temperature change..this is bcos magnesium alloy is very strong but brittle in nature..and also due to the thicker walls of the engine block..very susceptible to brittle fracture if there's a sudden change in temperature and under stress (this is what happened to the TiTanic)...my advice..is stay put in your car if theres a high water table during a flood...
