Our USA-assembled MAP sensor uses a universal keying that is compatible with pigtails for 1, 2, and 3 bar MAP sensors. Older sensors required a specific keying to match the connector you were using. This sensor works with any wiring connector keying variant.  Unlike the current Delphi production, this sensor is assembled in the USA. We strive to use USA-sourced parts whenever possible!

We’ve tested the cheap foreign-made knock-offs, and customers often come to us for a replacement after experiencing a failure with those. The generic knock-offs tend to literally fall apart, leaving you stranded. In our experience, these USA-assembled parts have had zero such issues.
