MAF Mass Airflow Sensor
The 1.5/1.6l Mass Airflow Sensors are a little too sensitive, quickly retrieving wrong data, therefor malfunctioning.
1.5/1.6l compatible Mazda performance MAF:
OEM Part No# L321-13-215 (expensive)
Taking the MAF from the 1.8/2.0l models to the smaller engines does not work.
You can also order the 22204-21010 /
22204-22010 for Toyota. They cost less than from Mazda. (Thx to MaverickR for the hint!) |

|
Knock Sensor
The 1.5/1.6l knock sensor is used with a LOT of mazda models and other manufacturers (e.g. Subaru,Toyota).
Nevertheless you should consider replacing the old sensor with the blue cable (ZL01...) with the new one (black cable):
OEM Part No# ZL02-18-921 |

Ignition Coil
If you encounter problems, there are revised versions of ignition coils available:
