Hey! Is there a cold air intake with a by pass valve because i live in québec and... you know the weather is like the worst on the world.

 

If you really MUST have a bypass, buy a CAI you like, and a bypass valve. Take the CAI to a muffler shop and have 'em cut it, or cut it yourself, and install the bypass valve.

 

or just buy a 2-piece CAI. Look for someone selling their old RRM one when the turbos go on sale.

 

I think AEM themselves are making a CAI for the RA (it says "pending" on their site,) which should work with their bypass valve out of the box, no cutting, no nothing.

 

I'm told the bypass works just fine with the Injen CAI, and I'm hoping I'm told right. My parts should arrive tomorrow, then on my next available day off I'll install the stuff. Once done I'll let you know how everything works. You only need to cut if you get a one-piece CAI.

FYI, though, neither Injen nor AEM will honor their warranties if you put the AEM bypass on the Injen intake. If you're worried about warranties, wait another month or two for AEM to finish making their intake for the RA.

 

yeah i will wait after winter anyway so i should go with the AEM one...

 

You just have to make sure the bypass valve is the same diameter as the CAI pipe. I'm personally waiting for the AEM to come out.

 

Yeah, the aem bypass works with the injen intake, you just have to get the right diameter bypass valve. Personally, i would go with injen over aem any day when it comes to intakes. Just my opinion though

 

I have both the bypass and Injen CAI in my possesion now (but not installed). A 2.75" bypass fits and there should be no problems.

 

Lesson time for the newbie: bypass valve allows air to be sucked in when the air cleaner is submerged? I ordered a SRI because in bad rains where I live I drive through water up to the bottom of my door just going into my driveway. Does the bypass valve solve this when using a CAI?

 

Here's how the bypass works: when the filter on a CAI is submerged, it increases the vacuum inside your intake pipe. Normally, your engine would just keep on sucking until it choked and died on the water. When a bypass valve is installed, the increased vacuum pulls the valve open before water is able to be sucked up the pipe, instead pulling air from inside the engine compartment. When the filter is no longer submerged, the valve closes and all is back to normal.

 

Thanks otter. So after the filter is out of the water and the bypass valve closes, is the residual water in the filter enough to kill the engine? I guess not, but I could not afford ($) hydrolock. Are bypass valves pretty much foolproof, or do they sometimes fail? In my area water to the bottom of the door is not uncommon in spring and fall.

 

My understanding is that mist getting into the intake is not enough to hydrolock, that it must be submerged. Looking over the bypass, the only way I can see it failing is if it gets stuck open, it can't get stuck closed unless installed wrong.

If you're really worried about it, the Injen CAI (and probably the AEM one when it comes out) can be setup in SRI configuration. Maybe have it like that for winter, then when the dry months come, put on the cold air extension.

 

Hey all, I got the Injen CAI installed with the bypass, and it fits fine. Took a bit to get everything lined up right, but everything is solid now.

BTW, I tried my hardest to install it without removing the battery(I didn't want to have to reconfigure my stereo), but it's just not possible.
