CAI
short ram
V2

if you could explain what each one does.

 

Cai goes from the throttle body down into the fender.....a short ram sits around where the air box originally was and a v2 is the same as a cai but it is thicker....a great recomendation for a b series engine is a jays racing short ram...you can find it on robearracing.com

 

Click AEM Power and read AEM's explanation of them.

The V2 is a patent pending technology developed by AEM. It's a dual piped design that uses the resonating frequencies of the intake charge at different rpm's to maximize air velocity.

The short ram is just a more efficient design than your stock airbox because it has smooth innner walls, only one bend in the pipe and should have a better, more free flowing air filter.

A CAI is positioned outside of the engine bay where temperatures are high in an attempt to draw cooler air into your intake. For every 10 degrees F you can cool your intake charge you will get ~ 1% more horsepower. Temps in the engine bay can be 50-100 degrees higher than ambient temp, which could translate into 5-10% more Hp out of a CAI over a SRI.

...or I could have just made all of that up to sound like I know what I am talking about. You decide.
