Just took my acoustic valve out...

If your old valve had failed or seized in the shut position or wasn't opening all the way it's 100% possible removing it will make the car feel better, you might have just got used to the slight reduction in performance you had before. That's assuming the valve is the only intake, if the air box has got another opening I might be chatting s**t.

Ph2 airbox has 2 intakes, just junk the flexi hose to the acoustic valve if you think it`s not opening.

Wtf? I'm sure this came up in the feed somewhere so I didn't think to check the date! Bumping an 11 year old thread is good going
