Cold air feeds are supposed to be at least 50cm of the floor otherwise it's just a water scooper  ;D

    Ever seen how low K&N Typhoon's are mounted? They do have a reputation of being water pumps though lol

    The grill where I plan to put it will be fine unless I plan to start fording rivers  ;)

    Just been reading Squadra tuning and it seems the that the Multiair is quite receptive to intake improvements, they are seeing ~ 8hp with open filter, gains stronger in the 5-6k range, so a drop in panel filter will help anyone that is not interested in a drill job :)

    They've also measured the Mito QV @ 163hp, Punto @ 165hp, Giulietta @ 170hp (it has a bigger intake, might try and take a look at one)

    Seems they were also able to independently tune the sport switch modes and throttle mapping for the Giulietta probably possible on other models, so someone who can get in the ECU could be quite handy.

    Hi, im looking into getting an APE and saw this thread, just thought i would contribute.

    It's always been my understanding that cold air induction kits on turbo cars arent really relevant, I.e the air passes through the turbo (big hot thing) anyway and is heated slightly hence the need for an intercooler.

    Look at jap cars, Hks mushroom filters straight on the turbo intake side but they have massive FMIC's

    Now i understand cooler air is denser and all that and more air into the engine is better too but would you just not be better off with a larger intercooler or a cooling system for the intercooler?
    along with a panel filter/open cone?

    With the trumpet/duct removed/kept in what difference does it make, I've just started a thread asking about this but it hasn't seemed to gain any attention. I was just wondering as I'm soon to fit a BMC Panel filter and wanted to know if I should remove this duct/trumpet out of the bottom of the air box?, it seems some people tell you to remove it, but for what reason? - Not sure if I want to pursue this mod just yet as it's still under warranty, but definitely a job for the future! Great Idea!

    Thanks in advance, Olly.

    Hi Olly,

    With a BMC panel filter it does say to remove the trumpet, real easy job just undo the airbox, lift out the old filter with the trumpet and place the new filter in.

    I did read somewhere though that removing the trumpet might have a negative effect as the air is not being sucked in so sharply, anyone can confirm this?   

    I also wanted to add the to post that I've also been told that a panel is better than a cone on the APE due to the layout of the engine bay, and that a cone causes a performance decrease once the engine warms up.

    please let me know if this is wrong.

    Hi Dan,

    I've sent you a PM regarding this, have a look at my recent thread/the PM and let me know your thoughts :)

    Thanks, Olly.  :thumb:
