can't understand why they are asking $50 + for them:confused24:

even if they work theres only a max $5 value there

if there are any gaens from a bit of swerll they would be minimal

Those things may work in theory, problem is, what's the path to the cylinder.

Our engines have 2 intake valves. How's that vortex you create gonna split into 2?

 

To use those, the entire intake path would have to be designed to take advantage of it.

Vortex generators.

 

Remember how spinning a 2 liter bottle upside down it will empty faster because of the vortex you create.

Same principle.

its suppose to make the mixture swirl and induce a better cleaner bern would like to see some proof of its effectiveness before considering it though

I remember reading an article years ago when Hector was a pup, that the thing to do was to enlarge and polish the intake ports not only on the heads and on the intake manifold. If I remember correctly what happened was they found out that the roughness of the manifold and intake contributed greatly to causing a turbulence for the inductance of fuel and broke up the air/fuel mixture caused better burning of the mixture. When they polished the runners they eliminated the turbulence and reduced the burning properties.

That's true, this is slightly different as some engine designers actually design the intakes to get a type of vortex into the chamber. It has to be designed as a complete system.

Not just some insert you put in the path.

 

 

Crap, now I'm just typing to hear myself typing.................

I saw these a few years ago made for cars and trucks(I was an auto technician for GM cars specialized in tune-up and emissions) had several cars come in with these things installed,checked the burn on some of them with the infared scope and they made absolutely no difference,just a gimmic,kind of like putting cow magnets on fuel lines in the 70`s and 80`s before fuel injection.
