OEM replacements
mazda protege 323 intake   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.

Engine swap

The easy way ? Not really !
mazda protege 323 intake   If you don't want to enhance your engine, you still can import a original JDM engine for a pretty small amount of money, but pls think about the labor costs and potential problems with emissions legality. And the JDM engines do use a JDM ECU, so GET this one along with the engine or you are doomed!

Most probably you would want to swap
FS(-DE) (130hp) to FS-ZE (170hp)
ZM/ZL(-DE) (88-103hp) to ZL-VE (130 hp S-VT)

Contact:
Corksport (US)
or your local mazda dealer but watchout for pricing (usually brand new engines are about 3500US$).
