Thread: MPS6 Airbox modifications- Review

    Arrow MPS6 Airbox modifications- Review

    Hi Everyone,

    After some searching i found the so called 'airbox mod' for the Mazda 6 and MPS.

    My 2000 WRX having a similar setup stock air-box and doing a similar thing to it and loving the results (removed in guard resonator, removed engine bay air duct, fitted K&N filter insert and inserted a 3" pipe from the airbox through the guard to just below the front bar indicator = a good ram intake + stock looking)
    ,
    i thought i would give this a go on the MPS as it could do with a better sound and a tad better fuel economy ()

    So referring to the pictures attached, i took out the resonator located in the
    front left guard and the flat plastic box located in the air-box itself. (Refer to my other thread regarding where the hell the MPS picks its air up from?!?)

    So far i this to report-

    1. It sounds deeper, a bit more growly perhaps
    2. No nice turbo suck \ whistle \ induction sound as yet
    3. Maybe a tad more down low torque
    4. Seems to have picked up a few points in the fuel efficiency department too

    Mind you i am running the stock air filter, and its quite dirty.
    Also noticed the AFM i very dirty also (i had a can of co cleaner but it was empty, not helpful lol)

    the reason i am investigating in retaining the stock air-box is purely for warranty issues.

    Next weekend = K&N Filter insert and CO Cleaner for the AFM.. I can guarantee once ive done that ill be a lot happier with my stock airbox.

    Good work mate, keep us posted on this. As I mentioned in the other post, I think one of us here could look into rigging up something for the CAI/SRI, might have to look into it for my CAI (when I get some time)

    Next weekend if i get a bit time, i would like to get both bonnets up on my WRX and MPS to compare induction setups and perhaps where there is room for movement \ improvement for the MPS.

    Thanks
