Ok someone has mentioned this EGR thing once or twice around here. And all i can undrstand is that it has something to do with the emissions?

Could someone please explain into some detail what this is and does?

Those plates are useless. Blocking off your EGR lines will not improve performance. When the engine is in low to mid throttle, exhaust gas is recirculated into the engine to lower the peak combustion temperature, however at or near full throttle, no gases are added to the intake. Those plates will not give you any increase in peak horsepower, are a waste of money, and just give your car bad NOx emissions. I have driven around in a car with an OBD2 reader hooked up and watched the digital level of the EGR valve, and when you floor it, the valve closes. This is a bogus performance improvement.
