Defo without a doubt remove the mesh filter from the bolt, done mine 7 months ago.
I can understand removing a filter to help prevent turbo failure, but doesn't the new pipe come with a modified filter?
I've read much conflicting advice on this subject. I wish someone who knows rather then guesses, would write a definitive article.
MkIII VTR 1.6hdi Modutop, Climate Pack, 16" Alloys
It's a modified part designed to prevent premature turbo failure so yes leave it in, peugeot spend millions developing engines and modifying parts that don't perform as well as expected...
