    Default 2.3 intake on a 2.5?

    I think I remember reading somewhere that you can use the 2.3 intake on a 2.5 without issue. Can anyone confirm?

    A CAI or SRI? Yes, they should fit perfectly. I had my SRI on from my 2.3 onto my 2.5. The only issue is one of the mounts from the 1st gen isn't there on the second gen for a CAI.

    yes lizz @sharkbait has the 2.3L mazdaspeed cold air on her 2.0L but I would assume it would work on the 2.5L as well as my 2.0L has the AEM cold air for the 2.5L. just need to change the hoses and mount brackets a bit. other wise they both have had 0 issues and no CELS

    heres the write up I did way back

    For a SRI there's literally no difference installing on a 2.3 vs 2.5 other than an extra hose to work around.

    Might be a stupid question but what about the turbo inlet pipe on the 2.3 intake? the 2.5 RAI does not have one correct?

    A turbo inlet hose will only really work for the turbo 2.3 setup. The turbo is at the back of the engine compared to the throttle body at the front of the engine.

    so if I got the one I am looking at for the 2.3 and go to install it on my 2.5L...what happens with that inlet pipe?

    They don't seem to make cold air intakes for the 2.5 (that I can see). I looked around on the forum and have read that there isn't much diff in the setups and they are compatible with 2.5L.

    Default 2.3 intake on a 2.5?

    A 2.3 turbo intake will not work on a 2.5 naturally aspirated Mazda 3. A regular 2.3L Short Ram Intake WILL work on a 2.5L engine. I can not be positive about the locations of the mounts on a 2.3L intake setup because it has been a long time since I installed a Cold Air Intake onto a 2.3 or a 2.5. I have the 2.3 Turbo CAI and it will definitely not fit a different Mazda 3.

    To have a proper intake for a 2.5L engine you need to be looking for a 2006-2009 Mazda 3 intake for the 2.3L engine.

    This is a 2.5L intake



    This is the 2.3L Turbo intake

    Not the best photo, but the intake goes back beside the battery box because it has to feed into the turbo.

    Thank you for clearing that up.

    tho I am still not having any luck when searching for a CAI for my model (2013 mazda 3 2.5).

    Could anyone post names or part numbers of any CAI that would be compatible with my model?

    It would be much appreciated.
