The HOLDEN-COMMODORE-VT-VX-VY-V8-O2-EXTENSION-LOOM-RECTANGLE-1-SINGLE-340MM from Exhaust Systems Australia is a single 340mm oxygen-sensor extension loom with a rectangle plug, listed to fit the Holden Commodore VT-VY V8. It's a wiring lead, not an exhaust component.
What does an O2 extension loom actually do?
When you fit headers or a longer exhaust, the oxygen sensor often ends up further from the factory plug than the standard harness reaches. An extension loom bridges that gap so the sensor still connects to the car's wiring without splicing or stretching the original loom. This one is a single lead, 340mm long, with the rectangle-style connector used on these V8 Commodores.
Will it suit my Holden Commodore V8?
It's listed to fit the Holden Commodore VT, VX and VY V8 using the rectangle plug. The right loom depends on which connector your car uses and where the sensor sits after an exhaust change, so it pays to match the plug shape and the length you need before ordering. Send the workshop your model and we'll confirm the rectangle 340mm single is the correct lead.
When would I need this part?
Typically you reach for an extension loom during an exhaust or header install, when the relocated oxygen sensor no longer meets the standard harness. Buying the loom at the same time as the exhaust work means the sensor is plugged back in cleanly rather than left short or hard-wired.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men handles exhaust fitting and the wiring that goes with it across the Illawarra. We can supply this loom with the exhaust job so the oxygen sensor reconnects properly once the new system is in. Listed to fit the VT-VY V8 with the rectangle plug; confirm your connector with us.
