I was just overlookin Evolution Mass Air Pipe Upgrade on buschurs website when i came upon this...

PLEASE NOTE: You will need to order the K&N breather filter unless you are running a overflow bottle when ordering this part

I was wondering why did u need the breather? and if u dont have it what harm might come ur way? Reason being is becuase i currently have the AEM intake but never Knew u couldnt upgrade ur Mass Air Pipe w/o the breather?

 

The reason is the buschur intake does not have the nipple to connect to the crankcase breather. my injen does, as does your aem, I believe.

 

Oh sweet thanks bro, i could stop sh**ing my pants now....
