the fram boost commercials (at least to my dad and I) are stupid. they're just trying to rip people off when it comes to the engine roar. You don't neccesarily need the tube (FYI: the boost kit is 300 bucks). Just go and get a 60 dollar high flow filter and put it in your vehicle. If you have a hemi, the black label cover is held on by 4 or 6 clips, that'll make the engine louder too.
