Corsa B 1.0i 12v X10XE - How to fit the Ecotek CB-26P ?

[R2000]

Hi ive three questions, probably simple to most.

1. Does anyone know where to fit an Ecotek CB-26P to a Corsa B 1.0i 12v X10XE Engine? If so can you supply instructions and a quality picture for use. I have looked at the illustration from this link to the closest match but its not too helpful for me.

2. Has anyone had any benefits from using this Ecotek CB-26P Valve?

3. What problems may arrise from using the Ecotek CB-26P Valve?

The reason for me wanting to use this valve is to reduce build up of carbons created within the EGR Valve as im getting tired of having to clean it or replace, and for its fuel economy .

Many thanks for any assistance.
