Anyone have any experience with one of these?

That would be a piece of crap !

Dont waste your time and money on cheap mods like this, they never pay off.

I have a friend that had one of those. Thing broke apart and caught in the throttle valve... at least it didn't make it to a cylinder. They supposedly do work, but I'd look for a name-brand one. It works the same way the vortec heads do. Except since it's before the throttle valve, you have to be WOT (or near it) for the air to continue swirling past the throttle body.

I dont think it matters what brand it is, they are bogus claims on performance and gas savings.

Plus turbulance in the air stream doesnt improve performance or mpg savings either. These intakes are designed inside to direct flow and canceal turbulance.

It's about as good as those resistors you put in the IAC wiring to increase performance, gas wasters! :2cents:
