it doesnt work. Its a marine blower. none of those intake vortex type devices work. all of the air current in your intake gets diffused when it goes into the TB. if it FORCED more air (forced induction) it would work. theres only one product thats actually proven to work and thats a product by AEM. i dont remember what its called but they made a part that did what the vortex devices claimed. Difference between the AEM one and the others is the placement of the device. not sure if they still make it though...
