vortex vs open airbox(stock)

[Dr350super]

has anyone have experience with testing the vortex vs open airbox.
Is it worth paying so much money for a vortex,or is the difference not too much.

My dr350s has 5000km and is still original,i would like to have more power starting with airbox

Warum stellst du deine Fragen nicht hier?

@Matthias: Weil er seine Fragen vielleicht hier stellen möchte? Natürlich ist der Hinweis auf ein englischsprachiges Forum legitim, aber auch wir haben ja zumindest ein Mitglied, das ne Vortex fährt, nämlich den Ludwig.

english: You may contact our Member Ludwig - he rides a DR350 with a Vortex airbox. But you will get more info about the Vortex at the link Matthias posted. Have a search at MaxZuki and you get lot of stuff to read
