how important is the bypass for the aem cai? could i really f*** up my engine if i don't get it? i live in chicago and we get a lot of crappy weather(last few winters we got a ton of snow) if that helps.

If you suck a column of water up your intake, your engine is toast. But that should only happen if you drive through a foot or more of standing water. Personally, I'd sleep better knowing I had a bypass just in case.

hrmm....do most people who get the aem cai get the bypass?

all us chicago guys didnt get the bypass... You have to really drive in DEEP water for the intake to suck anything up. I say dont worry about it. Plus we DO get alot of snow.. but most of it is slush on the roads and thats too heavy (i think) to get sucked up into the intake...

This has only been discussed about a million times - I suggest you use the search engine to read all the arguments for/against it.

Bottom line however is:
No, There is a 99% chance you won't need it.
And in that 1% you can probably get away with it if you are careful not to accelerate in deep water.

However, if you don't get away with it, you will blow up your engine.

Any other minute questions about the bypass you can find by searching. Or click on the link about the bypass valve in my FAQ (link in my sig)
