Thanks for the info there..... I'd have used it if my car was a 3.0l but sadly it's a 2.5l so apparently it's not applicable anyway.Vornwend wrote: ↑Wed Dec 20, 2017 10:11 pmIts 2 pieces of foam inside a plastic tube that goes from the airbox into the bulkhead behind the dash. You can just pull the tube out at the bulkhead end and fish out one or both pieces of foam to change the level of noise you hear in the cabin - 2 minute job. I removed the smaller bit a few weeks ago and did notice a nice step up in sound, may try taking both out but a lot on here say that the noise is then ear splitting Like you I'm new to Z4 ownership , next on my list is the CDV delete.Steve.Eagle wrote: ↑Wed Dec 20, 2017 9:28 pm Please excuse my probably dumb question that's probably been asked a thousand times but what's the sound generator foam????
