I've searched here, and on-line but didn't find an answer to my question. On the passenger side of the engine, the intake tube has a "noisemaker". I understand I can get a different tube from a MKS or Police Interceptor or the aftermarket to remove this noisemaker. I am assuming that this noisemaker is making the sound that I'd like to eliminate....but don't know exactly what kind of sound it makes. Does anyone know what the actual sound is that this thing makes? EDIT: some on-line research tells me that this is a Sound Symposer. Looks like the Police Interceptor or MKS "pipe" for that location does NOT have the symposer. I'm going to look into getting one of these parts and see if it makes a difference. Or, perhaps first, I can just put a plug in the port where the symposer is installed to see if it makes a difference.
