Quick question, does the AGS-R make the blow of valve sound just like the Alta CAI or do I need to buy a separate BOV?

 

It does make the same sound. you can also quiet it down as well w/ knock out sound ports

 

I'd like to know...do you just pop some of those out to get more of the BOV sound? If so what does that do to the "highly pressurized" airbox they talk about in the product description...

 

You can hear the woosh and blow off sound a little better. I really did not hear a volume change when plugging and unplugging the ports. I ended up putting a Alta blow off valve on. The performance of the intake is great though especially when you upgrade the hood scoop.
