cold air intake

  1. CARB Legal CAI?

    4.5 Generation Altima (2010-2012)
    Hello everyone, so I'm pretty much new to all of this. I have a 2011 2.5s, and I'm looking into modifying it. Obviously the first thing everyone does with a new car, is install a CAI. But I can't seem to find one that will work in California. Any suggestions?
  2. Intake Question

    Intake & Exhaust
    hey guys, im new to tuning up cars, but i was just wondering. if i were to get a regular JDM cold air intake for my car, but change the filter to a K&N filter. would that be the same if i were just getting a whole K&N Cold Air intake? does the piping make a difference??
