whats up guys... I haven't try this on my R2C intake yet but a friend of mine did this to his Stillen Intake and he said the Throttle response and MPG improved enough to be noticeable.
Power Crazy? - when installing a cold air intake, replace the black hose running from the engine CAMS to the Intake Box. Eliminate the hose and install 2 small air filters on each end called (CAM breathers).
heres a picture of the air filter: it cost about $10
when i get a chance, i will pick up a pair from autozone and give it a try..
i just want to share it with you guys if anyone wants to try it too.

 

Yea, this is common with motorcycles as well. I have done this on my KLR650 anything helps in regards to allowing the engine breath easier. Post some pics if you put em on!

 

This is nothing new.

Positive Crank Case Ventilation is what it is technically called.

It shouldn't effect throttle response in any way, shape, or form.
