  I didn't know the stock intakes went up the pillar.
  I do know a cold air path into the intake is remarkably effective in
producing better power.  Racers go to all kinds of lengths to get the
coolest intake air possible because as said, it's denser and has more O2
among other advantages.   That brake duct hose is waterproof, too.
