    K&N Fliter or Air Intake Performance Kit

    I am looking for words of wisdom (and experience) and advice on improving my
    '99 performance.

    Should I just get the K&N replacement filter (~$40) or purchase one of the
    aftermarket Air Intake Performance Kit (~$230)?

    If it's the kit, which one do you recommend and where is the best place to
    purchase it.

    TIA,
    - Pat

    The MonsterFlow probably offers the most performance for an NB:

    They claim 10 hp. Don't bother unless you get the CoolBox with it. Not
    CARB approved in California, and foam filters don't filter as well as
    OEM paper.

    Or, if you don't have cruise control, the Randall duct is much cheaper
    and delivers cool air while retaining the superior stock filter (5 hp
    claimed):

    In either case, don't expect more than a just-noticeable difference--on
    a stock 1.8 Miata, the intake is not a source of restriction, though
    cooler air is always good. Avoid K&N and other intakes that don't draw
    directly from an outside air source--all you'll get is extra dirt in the
    engine, and probably a power loss. The K&N advertisements are...let's
    say highly imaginative.

    Your performance dollars will work harder in the suspension than under
    the hood. Alignment, tires, shocks, and swaybars will make real
    improvements in your car's capabilities. A driver's school will make
    real improvements in yours.

    Does anyone have experience with the FRAM AirHog cotton filter?

    I've had the Monsterflow on a 2000. It sounded great at WOT but the
    performance gain was hardly noticable.

    3 years ago, I did some testing of underhood temperatures. As I recall, the
    temp at the Monsterflow intake quickly went up by 30-50 degrees over ambient
    when stopped. Within a half mile after a stop light, though, it went back
    down to ambient plus 10 degrees, the normal temp while driving. From this,
    I suspect that ducting cold air into the intake would do more than any air
    filter.

    I'm working with my third Miata. I don't push the handling anywhere near
    the limits car but I would like a little more zip around town. The single
    most noticable improvement I have found was advancing the timing (it can be
    done with an M2, BTW). Oh, I've made exahust improvements and tried cold
    air intakes on both an M1 and M2, and I found that I spent lots of bucks
    and got little improvement for my money. I've decided to either leave my
    new Miata stock or follow Leon's example and install a supercharger -
    anything else seems like a waste of money.
