Hello Rumcajs,
I got my Tilix and needles valve. I was planning of installing it without blocking the EGR valve. On what i understood, the EGR valve lower the combustion temperature when the catalyst converter get too warm. That sound like a good think to me and that is why i planned to keep it as design.
I have the provent 200 and need to clean my intake. My Patrol 2004 zd30 have 230000km.
Do you see a disadvantage of installing tillix without blocking the Egr?
Regards,
Vincent ;
