I just got my "other cai" from e-bay and was wondering what is the difference in this bypass http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33621&item=2457172824
and aem's??

It is made by some random guy with enough knowledge to create a bypass valve. (probably out of his basement or garage) It really is a simple set-up, but again I wouldn't trust it. On that note, I would also like to suggest that a bypass valve altogether is a waste of your time and money. You WILL lose a noticable amount of power, and it is not necessary for application on the Tiburon. The CAIs developed for the Tib sit right on top of the fender well, it is very well protected from the elements. Not sure if you know this, but if your filter gets wet, its not a big deal, whether you have a bypass valve or not, it will not hurt your engine. In any event the bypass valve ONLY works if the filter is submerged in water. It is highly effective, however it is only effective when it is completely submerged in water, otherwise your CAI acts the same way, whether or not you have a bypass valve. In SUMMARY, dont waste your money.

Thank you very much---just dont want to lock up the tib

i don't think everyone would agree with you on that point. It all depends where you live and how much precipitation/flooding you get in your area. Also, the BPV is highly recommended for cars that are dropped a couple of inches...i have cai w/out bpv, but i'm getting one pretty soon. there are a few members on this site who hydrolocked their engines...my .02 cents

risk hydorlock in case of some freak accident? or pay 40 bucks or whatever to never have to worry about it?

seems like an obvious choice. you have a new car, don't be a cheap ass.

This is why I put this question on here...to get different opinions. I think I will go with the bpv. But my original question is what do all of you think of the bpv I have posted.

Ok most likely this is a really ******* of a question. Technically its really up to the person if they get a bpv? Obviously depending on where they live correct? My only request is if it would be possible for someone to post links for bpv. I cant seem to find any, other than that homeproject one that got posted here.

It's not a ******* question. If you feel you need a BPV then get one. You won't have to worry about hydrolocking. If you dont get one, just use common sense and don't drive through pools of water that will be able to touch the filter. Also, dont start your car if there's a huge flood and you know the filter is submerged in water. It's pretty much logical.

What kind of links are you looking for? To purchase or to find out more about it?

lotus sumed it up pretty well, i live in florida and have yet to get a bpv, i plan to maybe get one before summer when the roads actually get very flooded since i have daily things to do and can't really control when i have to come home or not, also if your filter is submerged in water and you have a bpv will the engine still keep running and the car keep moving through the pool of water? i havent seen that question asked at all
