Why you need it

Headers move the sensor.
This puts it back in reach.

A

The problem

Long-tube and triple-stepped headers place the O2 sensor bungs further down the primaries than the factory manifolds. The standard sensor lead simply won’t stretch that far.

B

The fix

This harness plugs in between the sensor and the factory loom, adding the length you need. Square-plug connectors match the factory items at both ends.

C

No butchered wiring

Nothing gets cut or spliced. It plugs straight in, so the loom stays factory and the job can be undone at any time.
