if i was to get a CAI for my maxima, how would i be able to put a bypass valve on it since the MAF is in the way and do you need one?

 

no help?

 

The question isn't 100% clear. Can you re-phrase it?

If I'm reading it correctly you want to install the bypass valve on the CAI?

From my understanding it's a complete waste of money and defeats the purpose of the CAI. It makes it a WAI/CAI... My advice is don't get one.

 

The bypass valve goes on very easily. You take the rubber sleeve that is between the MAF and the "bend down" off. Replace it with the bypass valve. It is almost an exact fit. Atleast it was for me.

As for usefulness and what not, I put it on as just peace of mind. I'm not dumb enough to drive into a 6" deep puddle but I also wanted a little safety net.

As for making it work like a HAI, that's completely untrue. The bypass valve has these plastic flaps that only open when there is vaccum in the opposite direction from normal. So, while the CAI is not full of water, the bypass only sits there and does absolutely nothing.
