I have a friend who told me about this devise three months ago and explained how it would increase airflow, like getting the fluid swirling and dumping it out of a two liter bottle. It definitely will empty faster. Try it. However, he bought two of these swirly gigs, one for each of his cars. He has a mid 90s Taurus, and a late 80s Trooper. He said that he thought he maybe could feel a little more torque at low end on his Trooper, but it had no noticible affect on his Taurus.

So, Spend your hard earned dollars on a K & N filter and other intake and exaust mods, not the Swirly gig.

I wasn't advocating or supporting their theory of swirling air being able to enter faster into the engine. Simply stating that example as they did to my friend when he called them to get more information. Actually, I believe it is Tonado Air not Swirl Whatever that uses this water evacuation example to sell their gadget. Unfortunately, he, my poor gullable friend, bought the whole package. Fortunately for me, he was honest enough to himself and me to admit it didn't do much, if anything.

I hope that clarifies, if their was ever any cloud.

Good luck.
