Should I block off my EGR valve?

The EGR Valve (Exhaust Gas Recirculation) valve is found on almost all modern engines and is considered part of the emissions package of your vehicle. In some states, removing it will cause you to fail your emissions inspection.

Does removing EGR increase power?

Yeah,

EGR doesn’t affect the running

of the engine – MPG or power – other than fouling the inlet; it’s an emissions device only. It’s specifically programmed to only operate at part throttle and cruise conditions, so it simply doesn’t affect response or power. It also doesn’t affect efficiency…

What happens if you delete EGR valve?

Installing an EGR delete kit

reduces costs on repairs and fuel costs

, as well as decreases soot deposits that an EGR valve produces. Disabling it prevents harmful contaminants from being reintroduced back into the engine, resulting in problems. When the engine’s performance increases, so does the fuel economy.

What does blocking the EGR do?
