Put in factory air box and.......

[Mean Green]

Put the factory air box back in my GT and my HSK BOV doesn't make a sound anymore. Is it because of the factory turbo up pipe that runs up to the air box? I know I couldn't hear the factory BOV until I removed the factory pipe. Does that include making my aftermarket BOV silent, too with the factory pipe?

Mean Green. I don't think that is the problem. I have the stock box-with the exception of a K&N drop in filter- and I can hear the Mopar BOV pop off. Fairly loud too.

I have the HKS BOV like yourself with the factory airbox and there is no trouble hearing the BOV. I would check the small plastic filter that came with the kit that goes on the vacuum line. Mine started to separate after maybe a months use and eliminated the vacuum.

I put the aftermarket CAI back on and I can hear the HSK bov plain as day. I reinstalled the factory air box and I can't hear the HSK bov again. What's up?
