B&B Cold Air Intake.... - Benzworld.org

l know some of you guys will get upset, or you will say "l told you so"...but l had to try the B&B Cold Air Intake on E-Bay.....if you look at the description..it sounds incredible....so off l went..The install is about 20 minutes, no biggie..l unhooked the negative terminal on the battery to reset the MAF sensor to allow for more air..(for 15 minutes)...l tell you.l did this Thursday morning, and for the rest of the day it felt great and sounded even better..What a "Throaty sound".....Certainly more responsive....Then came Friday morning..the dreaded "Check Engine light"...l don't understand this..My MAF sensor was replaced less than a month ago...so l know that is not the issue....and JD has the Kleemann Supercharger on his ML, with no problems...and it's receiving alot more air than this little CAI..so what gives here...Any idea's....[V]

mas reading more air and its catching oils from the filter.

the person with the supercharger is most likely using a chip that has his blower factored in.

So there is no way to re-set the MAF to accept more air..l find that hard to believe...What would happen if l removed the entire MAF sensor..just curious...

NO MAF = No Data for computer to calculate air/fuel mixture ... run? actually it might .. but you'll run super lean

as it get super lean ... things get hot .... then hot leans to breaking stuff .... on and on

Sorry..about the "lame" question..l'm not really a "technical" guy....[;)]

Thanks for the heads up. I'm thinking about a air intake for my 01 ML430. I wonder if it's worth it. I'm not a technical guy either.

Mine came with a whole new ECU, not just a flash to the old one. The light MAY go out if the engine can learn about the new airflow and it's also possible that the intake had enough dust in it that it fouled even a new MAF.

i have a cold air intake...similar to the one in your link...i have no issues. made sure of proper bend angle, and proper lube amount.

your CE light will not go away...your car cannot learn about the new airflow quantities. dust isnt the reason for ruining the mas...oil is.

lf this is the case..what prevents your CAI from tripping the MAF sensor....l would like to see if l can get mine to work.....[V]Any suggestions "A", Are you trying to say that the MAF has a limit to which, it cannot be exceeded[?][?]

what prevents intake from tripping mas?... bend in intake pipe. reduces the airflow to the sensor... also isnt as effective, but still provides the desired effect.
yes, the mas has a set value of air that can be read...once that is exceeded by a certain amount...ce light.
