I looked into the vararam and was damn near sold on the thing, but i looked into it more and some people said that the plastic and pieces weren't the best quality and sometimes didn't fit or line up.
I went with the S&B CAI which is an under-glass intake with an option for the under number intake scoop. I chose against the lower intake tube because:
1)you'll never be running at a fast enough speed to make a big enough impact
2)if there is enough air to create a positive pressure, similar to forced induction, it won't hold the pressure. The positive pressure will just go back out the other intake inlet and not into the engine, simply because air will always travel in the path of least resistance.
3) its almost quite literally a shovel. If you drive (anywhere) it will pickup anything that other cars tires kick up. If you off road at all or drive on the beach or in the snow, you're almost guaranteed to fill it with crap and render it useless.
The negatives outweigh the positives for that one because it isn't a true forced induction.
But back to the Vararam, for the same price and about the same power increase, the S&B is the better buy. Customer service is absolutely awesome too!!
