I mount my Apexì Power Intake and sometimes i heard the sound of the Blow off Valve.
But i never mount the blow off valve.
It make when i shift the gear in fast driving.
Should be everything normal correct???
Thanks

When you replace the stock airbox with an aftermarket( apex specifically) You will hear the BOV more because it is now vented into an open air filter element instead of the enclosed airbox. Everything sounds normal too me.. How does it feel when driving? ( power wise) Aloha, Dave

 

i have it from few time, and i still have to set the boost controller; so is too early to say you how is going i think will be a little better.
Thanks

 

Pietro ti senti la BOV perchè HAI la BOV
è di serie sulla '7

ciao
