Starlet don't have an air flow meter, the n/a has a temp sensor near the air box but it's bolted in to the manifold on the turbo, starlets measure air from the map sensor which is a little black box on the bulk head on the drivers side it has a 4mm tube going to it and it will be mounted higher than the manifold in the 4mm tube it will have a small inline filter about 3-4 inches below the map sensor.
