What components are shown in this intake diagram?

The diagram labels four components: the intake manifold ('intake mani'), the airflow meter, the turbo, and the intercooler, connected by lines representing intake plumbing.

What is the purpose of the callout in the drawing?

A callout points to a small circle near the turbo/piping labeled 'little nipple that do not know where it goes,' meaning the uploader is asking where an unidentified nipple/port should connect.

Does the diagram show the airflow path?

Yes, in general terms: the airflow meter connects to piping leading to the turbo, which routes through the intercooler and then up to the intake manifold.

Does the document include part numbers or specifications?

No. It is a simple sketch with component labels only — no part numbers, torque values, or other specifications are shown.

This document is a simple hand-drawn (computer-sketched) schematic of a turbocharged engine's intake air routing, uploaded to the gallery of a 1989 Mazda MX-6. The drawing shows four labeled components connected by lines representing air plumbing: an 'intake mani' (intake manifold) at the top, an 'airflow meter' at the right, a 'Turbo' in the center-left, and an 'intercooler' at the bottom. A callout line points to a small circle on the turbo/piping area labeled 'little nipple that do not know where it goes,' indicating the uploader drew this diagram to ask the community where an unidentified vacuum/pressure nipple on the intake tract should connect. The routing depicted shows air flowing from the airflow meter through the turbo, through the intercooler, and up to the intake manifold. The document contains no part numbers, torque specifications, wire colors, fuse data, or stated year/model applicability — it is purely a conceptual layout sketch of the intake system with a question about one unlabeled port. A reader can learn the general arrangement of the intake components as the uploader understood them, and the location of the mystery nipple in question.
