Which should i buy??

The 2nd ones for $289 a pair.

I bet the 1st ones will definately add alot more air coming in a prob a few hp because of it but you have to wonder about the other side where it pushes hot air out, that scoop design looks like it brings air in but maybe they forgot the other side pushes hot air out, looks like it would bring in more air than it would push out.

Actually, that's a common misconseption, the vent on the passenger side has a fan that pulls cooler air into the hot engine area when the car temp gets to a certain degree. I know this is true becasue the last time my car was parked in the garage and I heard the fan kick on, I ran over to it and held a paper towel up to it to see which way the airflow was going and it almost sucked it into the vent.

By the way, you can find the C.F. vent like that on e-bay for $199.00
