Its pretty simple. I just put on my AEM cold air intake, and it has to be the best sounding intake on the market, + it has the highest horsepower gains. The short ram intake, doesn't make as cool of a sound and doesn't get u a horsepower gain. So, if ur in the market for an intake, go get an aem cai.
I did not get the bypass valve for one reason....you won't ever need it. Literally, u'd have to drive through a puddle about 2-3 feet deep for it to hydrolock, and I sure hope u don't drive through puddles like that in ur Teg.
Good luck wit ur Teg!!
