Garbage- avoid it like the plague. I didn't buy one but saw another thread where a knowledgable person explained how it works. It basically tricks your cars computer to change the fuel/air mixture or something like that. It sounds like a good way to destroy your engine.
Those are nothing more than resistors, that tap into your IAT sensor to trick your engine into the thinking the incoming air is colder than it is, and the engine will react by adding more fuel. You may get a little more power, but you will most likely note a drop in fuel efficiency.
While this device is a scam, the devices we sell DO improve performance and fuel mileage, they just cost a little bit more
