FOSTI F31 air flow sensor

FOSTI F31 air flow sensor: the photo marks 100 mm, 27 mm and 22,50 mm, and the part itself is not a separate sensor but the whole throttle body assembly with two connector blocks. Compare the port diameters with your intake duct.

• We measured the arrow ends: the 100 mm line runs from the top of the black module to the bottom of the assembly, the 27 mm rests against the inner edges of the wider port, and the 22,50 mm against the inner edges of the narrower port
• So 27 mm and 22,50 mm are the inner diameters of two opposite ports, not the body width
• The photo shows a throttle plate with a small screw, a return spring, a cable bracket with a fork, and two mounting legs
• The body is cast with 30A-04 and 18L12A, and a label with S 5K is stuck on the black module
• Two separate plugs are connected to the assembly: one black, one grey — that is two different sensors or actuators, not one sensor
• So the name talks about an air flow sensor, while the photo shows the whole throttle body assembly with sensors. We show both sources and do not choose the manufacturer for you
• The photo gives no threads, no distance between the mounting hole centres, and no voltage

To be straight with you: which of the two plugs belongs to which sensor, and whether the assembly is sold with all its parts, the maker did not specify, and we do not guess. Before ordering, measure the inner diameters of your intake duct and manifold, send us a photo of the old part — we will check it before you order.
