| It's going to mess with your fueling by fooling the ECU into injecting more fuel into the engine, basically the same way your engine does during the warm-up choke phase. You may have slightly more power initially, but your emissions will go to hell and it will probably harm your engine by running too rich all the time.
Nobody be a muppet please.
Full marks to the guy for typing loads on the ebay page though, he put some effort in.
