Exhaust gas recirculation valves (EGR) were introduced in the car market as a way to reduce gas emissions before DPF’s came along. Manufacturers created a way to recirculate already burned exhaust gases again by directing them back to the intake manifold in order to be re-burned and this way lowering their emissions. This is basically the function of a EGR valve. So why would you have an EGR delete? The main problem of the concept is that this exhaust gases bring a lot of engine oils and fumes, that after some time tend to block the intake manifold lowering its efficiency dramatically.
