  3. Upgrading, 2.0 Sport to 2.5 grand touring

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So to answer a question I’m sure much of you have, even though my 2.0 is tuned the 2.5 is still more powerful in the top end. My 2.0 currently has Headers, midpipe, axelback, and a SRI. It is tuned on 91 and e85 and although the 2.0 is faster to 60 the stock 2.5 just blows it out of the water...
  4. Upgrading to an Optima battery?

    2014-2018 Mazda 3 Skyactiv Discussion
    Anyone out there, who replaced the standard battery by an Optima Red Top on a (European) Mazda 3 2014 BM? I had an Optima red top in my former Mazda 6 for several years and this battery did a great job. So, in the near future, I planned to switch to an Optima Red Top (RT C 4.2, RT R 4.2 or RT S...

    2014-2018 Mazda 3 Skyactiv Discussion

  6. Upgrading a 2.5L

    Engine / Drivetrain
    I'm pretty new to the forums, I registered but never posted, but I'm disappointed to see there is a mod and more forums for the 04-09 mazda 3 and almost nothing mod-centered for the 10-13 mazda 3. Anyways, I have a 2012 Mazda 3 s GT 2.5L with 70 durameter mounts for engine and trans, coilovers...
  7. Upgrading from Firmware Version 59.00.330 NA N to NA 59.00.441A?

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    I decided to finally look into installing AIO Tweaks, it's definitely overwhelming at first. I'm on version 59.00.330 NA N, and am going to upgrade to .441 before installing the tweaks. Since I read another thread where that's the most stable version that you can still tweak on. I found a...

    Hi all, Im new here! My name is Ahmed! Got a question: I upgraded my CMU to version 59.502, and it seems the SCBC/SBS stopped functioning altogether (they used to work on v56). I have an unstable SBS option only under the "safety" screen. By ubstable I mean: I turn the option on, shut down...

  10. Is it 1 pair or 2 pairs of bulbs when upgrading headlights?

    2014-2018 Mazda 3 Skyactiv Appearance & Interior
    Hi everyone. Future 2018 M3 owner here, just processing some paperwork. As per the topic's title, I am a bit confused with upgrading the bulbs. From my understanding the 2014-2018 M3 uses separate bulbs for low and high beams, H11 and 9005/HB3 respectively. The videos I've seen upgrading their...

    Well, after cruising around this website for the last month or so, I've caught the Mazda fever even stronger and decided to trade in my current 2016 S Touring model for the latest and greatest 2018 3 hatchback.

  12. Anyone Attempt Upgrading USB Ports?

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    As the title says, has anyone attempted to upgrade their USB ports? As noted and buried in threads elsewhere (Ah, modern day acronyms. Too short to search. Too common to be worthwhile.), these ports are extremely out of date. I'm convinced this is one of the things alluded to needing to be...

    2014-2018 Mazda 3 Skyactiv Discussion
    I have the stock sound system on my Mazda 3 without the Bose "upgrade" and it sounds really tinny despite adjusting the EQ settings. Has anyone upgraded their system? preferably keeping the stock headunit but changing the speakers/amp?

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    Hello everyone, I got a 2016 Mazda 3 and I'm loving it, the only thing i wish i could change is the radio system, this is a Mexican vehicle so the basic model has a Radio in the dashboard instead of the navigation screen. I have requested a quote from the dealer for an upgrade (which is...

  20. Advice on upgrading Bose system-- Best bang for $$

    2010-2013 Mazda 3 & Skyactiv Audio & Electronics
    Hey, all! So I love my "new" 2011 s GT, but the sound quality is really irking me. I think the biggest annoyance is the fact that I can't adjust the mids... bass sounds acceptable, I don't need a loud "booming" bass, but trying to achieve a rich bass sound results in the mids getting lost...
