2014-2018 Mazda 3 Skyactiv Engine and Performance
For comprehension - the Axela is the Japanese name for the Mazda 3. A BM/BY chassis is the 3rd generation (2014+ in America... 2013+ in Japan.) The BM designation is for the hatchback (5 door) and the BY designation is for the sedan (4 door.)
Please be aware some of these parts...
