Our plate allows you to pull the EGR tube from the exhaust so that it will draw in fresh air instead of exhaust gas. The plate is then used to cap the exhaust on the header/manifold. Copper RTV recommended for optimum sealing. Exhaust side plate is threaded for use with factory bolt. Optional intake side is not threaded.

The proper way to install the plates so you should not get an SES light is to install the exhaust plate on the manifold, leave the EGR plugged in, but leave the exhaust side of the valve open to the atmosphere. Using this method will keep the PCM happy and you WILL NOT SET AN SES LIGHT or throw any codes! If you want to remove the EGR valve completely, you will also need the intake plate, however you will get an SES light, so you will need PCM programming.

With the EGR now drawing in fresh air your intake will stay cleaner and cooler. *Gas mileage will suffer about 1 MPG with this mod.

The intake blockoff plate is also used to block the PCV inlet on a Gen 5 blower when doing a Gen 5 swap on a Gen 3 blower car.

Egr block off

Installed the plates dry and they didn’t seal resulting in an exhaust “tick”. Reinstalled with some high temp gasket maker and sealed it right up. Cheap easy 20 minute install and have the piece of mind that my new upper intake will not get caked in soot or have the possibility of a hole getting burnt in it.

Not bad

They work very well very thick material I thought a little bit more engineering would have went into developing them but they do serve their purpose .
