        Easy part

        Good part and super easy to install. The oil line is a bit long but not a big deal.

        Super Easy

        The kit came with simple instructions and it was installed in less than an 1 hour. It was the correct length. I had no problems with it reaching my BBK long tube hearderst O2 Sensors.

        Worked great with my Longtubes

        Rather than splice wires together to extend the factory harness I decided to try this. It worked perfectly to reach the O2's in my longtubes

      LMR says 91-93 years uses a different pin-out. This will work with my 90 with manual trans?

      • This will work for 87-93 Mustangs with the 5.0 and manual transmission.
