2010-2013 Mazda 3 Engine and Performance
I just bought an used Mazda 3 GT 2010 (2.5L Engine).I'm so used to Honda that I can not tell if this engine sounds normal. So does it sound normal? Is that engine knocking or a normal 2.5L Ford engine sound? youtu.be/qva7fogPfAY
Also,(see pic) is this a hole/crack on the intake...
