    Cold Air Intake

    Hey guys , I recently bought an 04 wrx wagon. It has a stock filter at the moment, and I was thinking of putting in something better that gives noticiable power to the car. Which would be the best one, or a good cold air intake to put in? Not too expensive, I'm looking around $100-150.

    Thank you
    Ed

    An intake won't have any effect on power, and must be tuned for unless you feel like replacing your engine.

    I'm not sure whether a tune would be needed for an '04. For recent years (08 on), a cold air intake would mess up the MAF sensor calibration, but I believe that's not true for some of the older cars.

    Even if it's perfectly safe without a tune, it's not supposed to add significant power. (Some may like it as a noisemaker.)

    Cobb catted down pipe would give you a nice gain, add that 2 a cat back system. Then tune for best results.
