  1. Ceramic Coating for Exhaust Manifold: Worth or Nah?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So I've been doing a little reading and stumbled on the CorkSport aftermarket exhaust write up and did a little extra reading as to why the exhaust headers were designed in such a way by Mazda in the first place. I guess due to the high compression it creates a very hot exhaust charge and the...
  2. 155hp US spec engine vs 120hp/165hp EURO engine question

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hi, Recently I have just bought a 2017 Mazda 3 2.0 155hp US import, I'm located in Europe. The car has a badly cracked intake manifold besides other things and runs rough:).

  4. mystery foam inside intake manifold

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    My best guess is some sort of baffle for noise reduction as it is not attached to anything, just bumbling around in the void under the intake runners above the plenum. If you feel around, there are a couple more foam blocks that are attached somehow in that same space, anchored to something...

  8. 2.5 L Exhaust Manifold

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Thoughts on up pipe placement for this manifold (2.5L sky)? I was thinking having it begin before the flex, which would be replaced by a very short one(after the flex is too cramped). Then having a t3 flange on the exhaust inlet end of the pipe (no wastegate provision).

  20. Exhaust manifold optimization

    2010-2013 Mazda 3 Engine and Performance
    This relates to my other thread about TB optimization. I have the California emissions version of the 2.5L NA power-train and that means a more restrictive header. I don't want a CEL and would really like to still pass emissions. One option is an aftermarket header but CEL's are a problem, even...
