K&N Box filter

[bob12312357]

Does the drop in K&N filter really increase the turbo sound like a cold air intake just slightly softer? Will it give a real soft pshhhh between shifts?

No, an air filter does not make the pssh sound, a blow off valve does.

It gets a little more vocal if you swiss cheese the airbox. Not CAI loud by any means though.

The Cabrinio or watever the hell its called makes a very nice soft pshhh with the stock DV when u let off the gas,with a normal DV. Trust me I know what a BV is and I don't want a full on one.
