Installation Notes and Tips

Verify the valve type, backpressure requirement, and vehicle notes before installation. This Delphi EG10099 includes a gasket, but mounting hardware is not included. Confirm whether the application is listed as California or non-California, and check the note for vehicles without Close Coupled Exhaust where applicable. Clean the mounting surface thoroughly before installing the new EGR valve and gasket.
