Yeh does anyone know if these are any good and safe to use?

They just rubbish resistor-in-a-box things that will trick the ECU into thinking the air temp. is low and therefore more air enters the cylinders and its trying to aid on a cold start by pumping a lot more fuel. That thing will NOT improve MPG. Savmoney and By a reckognized unit for a good tuner: PSI Motorsport, Steinbauer, Wetterauer, Superchips, etc. They all are TUV approved and been developed on rolling roads so they not any gimmicks !
