Injen cold air. Waterlock prevention?? Everyday driving?

neveucd · 07-09-2010, 12:59 PM

I don't agree about the intakes...I went through like 6-8 inches of water not intentionally, but forced due to oncoming traffic from behind....intake sucked it up like a straw and killed the engine....in the shop now hoping it's not as bad as I know it will be.

keep me posted..... i am looking at aem's new cold air, but involves moving the water resivior and the mass air flow sensors are down by the filter so im wondering if this technology will allow to go through water without actually sucking it up being that the mass air flow sensors are down by the filter, will it restrict the air flow automatically? I am very curious because i am only making that mistake once, its not fun to buy an entire engine block....
ANYONE???

Why would that make a difference? A sealed tube with a filter on the end is gonna suck in water if you bury it, no matter where the MAF sensors are placed.

right but my point is if the mass air flow sensors are triggered with water with the computer system onboard should restrict any flow into that engine or cut it off... with the sensors right next to the throttle body its already too late... my question is should i use bypass valves and how much power will be reduced...

as u can see in south florida we dont have great drainage....

They may, but by that time it's WAY too late....The suction of 3.7 liters at whatever RPM's is something you can't get around. Water ingestion will be almost instantaneous. The only way to avoid sucking water is to NOT drive into it..
