O2 Sensor Extension Harness — VF Series 2 & LSA (Triangle Plug)
Extends the factory O2 sensor loom on VF Series 2 and LSA-powered GM cars, so your triangle-plug sensors still reach once long-tube or triple-stepped headers move the bungs further down the primaries.
Headers move the sensor.
This puts it back in reach.
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.
The fix
This harness plugs in between the sensor and the factory loom, adding the length you need. Triangle-plug connectors match the factory items at both ends.
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.
