The CAI/Bypass Valve Info Thread

Found it... http://www.trdsparks.com/displaypart...2&parts_id=520
That should work with the Injen CAI... But, now that I think of it, I can't remember if the 2 pieces come together before or after the maf? Eff it ill go look at my car tomorrow. I'd rather have a check engine light for unmetered air than a hydrolocked engine...

I have one of these bypass valves came with my injen cai.It has instructions on how to install and comes with a template to cut some where.They dont show any pics in directions on what your supposed to be doing.I even been to aem website hoping there would be more there.Just curious if anyone had a pic of what your supposed to do.The directions just seemed very vague and I like to be precise.

In my case I bought a injen CAI (no BPV included).
I decided after some local flooding that I needed a BPV so I bought an 3" AEM BPV off of eBay for about $50. The BPV goes inbetween your short ram tube and your cold air tube. The installation is a real b***h . You will have to uninstall everything in order to cut 1" from your short ram after the MAFS and 1" off of the cold air tube where it connects to the BPV. I used a hacksaw since I didn't have anything better. The cuts weren't perfect, but it got the job done.
I did all of this because I live in florida and we get a lot of rain in the summer. Sometimes roads flood here. If you live in an area where this isn't the case save yourself the frustration and don't worry about it. The only way to hydrolock your engine is to submerge your filter in water. I'm still a noob at posting pics, but hers's one below of the finished install. You can also see a pic posted by Djicey702 earlier in this thread for an idea of where the BPV goes.

I use to have the BPV on a 1997 Honda Civic with a CAI & it works I even went thru big puddles of water (not on planed just happened that way)
I think that the AEM BPV is a good idea for anyone running a CAI on any make or model car, truck or suv hell even a van

I have read many places not to use BPV with F/I. If the air intake tube that goes to the turbo has the same vacuum as the stock car which is around 26-28 in hg idling then if you modified the air intake tube that feeds the turbo it should work.

After putting in my injen CAI I have come to the conclusion that you would have to be diving through a lake in order to get water into your engine. on my '09 tC the filter is in a spot that it is virtually impossible to get water into without submerging your vehicle. Between the fender and bumber with a splash guard and wheel well covering it all. I didnt put a hydroshield or BPV on mine, but i also drive around puddles just to not push my luck.

I've been in the situation where I didn't have a wheel/fender liner. I had a '91 Civic which ended losing the wheel well cover because my car was so low. At first i would convert my CAI into a SRI when it rained. But after a while I got lazy and just left it like that. I even drove from San Jose to San Diego in all kinds of weather and never had a problem. I think the BPV would do just great as preventive measure. I also so the demo that AEM did and it was on an Acura NSX revving up pretty good but not WOT and they submerged the filter into a fish tank. No water went in. You could see it because they used a crear tube as the cold air extension. I wouldn't recommend doing what I did, I took a big risk, and I had to clean my filter out almost monthly.
