What is the EGR & should you delete it?

Exhaust Gas Recirculation (EGR) is a technique that reduces emissions by recirculating engine exhaust back into the engine cylinders.

This clogs intake systems with soot (which can have devastating effects on the engine), raises temperatures in the EGR cooler and causes the engine to burn more fuel in order to generate the same power.

This negates the EGR's original purpose of reducing air pollution.

An EGR delete removes the EGR valve and prevents exhaust from being redirected back to the engine.

The exhaust instead flows out of the truck. When you delete the EGR, you will notice significant fuel savings and noticeably better power and throttle response.

Just like the DPF, deleting the EGR requires installing a delete tune so your truck's computers get programmed to operate without it.

EGR delete kits are high specific to your truck's year/make/model. So it is crucial to make sure you get the correct kit.
