I think i have this problem as well! Anyone know what size the non return valve is? Is it 3/16" (5mm)?

I just did the opposite today and replaced my pop charger with the original airbox (+ rtbiscsuit's velocity stack mod) The pop charger was one of my first mods and while the noise is nice, the car feels much better with the airbox back on. I found that with the pop charger on there was always a slight delay in power when accelerating. Anyway i've got HFC's to provide the noise now

Thanks to tarmac i'm getting the berks\stillen\scorpion combo too

Hi Tarmac, if they're still available i'll take one
