That's on the N52 isn't it?Kenich said:DaveP said:The noise should come from the filter and intake hose itself, irrespective of sound generator.Kenich said:I found using the N52 OEM inlet hose with an open cone filter didn't produce much more noise. It might be due to the large resonation / type thing built into it I assumed. Someone in the USA was also doing carbon intake pipes, that coupled with this could be a good combo.
Yeah, agreed. I wasn't implying the sound generator was limiting the noise. Circled is what I assumed may of restricted the noise? I'm not sure, I just know when I popped the large Simota open cone on from the GruppeM (Without the carbon surround) onto the end of the standard intake hose, I barely noticed any noise difference.
I believe[ref]Jollygiant[/ref] is doing the initial development on an M54 which has a far simpler air box.
