    2014-2018 Mazda 3 Skyactiv Discussion

  2. 2011 Alternator

    2004-2009 Mazda3 Discussion
    Need some tips on replacing my Alternator. Tried to find a YouTube vid for replacing the Alt. There is a vid for every Mazda 3 model EXCEPT for a Mazda 3 2.5. Any vids out there? Any tips? Replacing Serpentine at the same time (why not)
  3. Chirping from Alternator

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Started to hear a chirping noise coming from the engine once the car heated up. Turns out it's the alternator? Apparently it's charging fine for now but when its getting hot it causes a chirp noise, and it's fairly loud. The quote I got said that an aftermarket alternator is around $350 and a...

    I want to upgrade the Bose audio system I have in my car by replacing all of the speakers and adding a subwoofer but I cant seem to find anybody that makes a high output alternator for the 2.5 skyactive.

  8. Where to buy H.O alternator?

    2010-13 Mazdaspeed 3 Engine and Performance
    I'm looking to upgrade my alternator, although I can't seem to find a company that makes them for the 2nd gen ms3. I called Mechman, Power Bastards, RPMstore and no luck. Power Bastards said that the reason why they don't specifically is because there are no one who makes quality internal...
