Blowback Tube

What is the blowback tube for anyways?

I was putting on my aftermarket intake and noticed that the blowback tube wouldn't reach the intake pipe. I did some searching and noticed that some people put a mini filter over the tube and some bought a longer tube to connect to the intake pipe.

Which is better or is there no difference?

What are you talking about? Do you mean the recirculation pipe/hose that connects from the intake pipe to the BOV?

From the words "replacing it with a mini filter" I can only think of the PCV line that runs from the valvecover to the intake pipe. If the vacuum hose is too short to reach the intake pipe, just buy longer hose!
