Model Year 22/23 RAMAIR induction kit knocking / clunking noise

[Thunderhead96]

Hi all, wondered if anyone could help. Recently installed a Ram air induction kit on my Formentor VZ2. There’s a clunking noise at the end once releasing the throttle (usually as it passes below 2000rpm). I have reinstalled it with no luck. The heat shield isn’t knocking on anything either.

Not sure how to attach a video on here

Any suggestions would be much appreciated!

Hi, it's normal, it's the diverter valve closing. Mine does it too with an APR intake; pretty much with any open intake it is audible.

Mate you're a lifesaver! Was going to upgrade the current stock turbo inlet hose also to see if that would resolve the issue
