The HOLDEN-COMMODORE-VZ-VE-V8-O2-EXTENSION-LOOM-SQUARE-1-SINGLE from Exhaust Systems Australia is a single oxygen-sensor extension loom with a square plug, listed to fit the Holden Commodore VZ-VE V8. It's a wiring lead used during exhaust work, not an exhaust part.
What is an O2 extension loom for?
Fit headers or a longer exhaust and the oxygen sensor often ends up further from the car's factory plug than the standard harness reaches. An extension loom bridges that distance so the sensor reconnects without cutting or stretching the original wiring. This one is a single lead with the square-style connector used on these V8 Commodores.
Will it suit my Holden Commodore V8?
It's listed to fit the Holden Commodore VZ and VE V8 with the square plug. The correct loom depends on which connector your car runs and where the sensor sits after an exhaust change, so match the plug shape before ordering. Send the workshop your model and we'll confirm the square single is the right lead for your car.
When would I need it?
An extension loom earns its place during an exhaust or header install, when the relocated oxygen sensor no longer meets the factory harness. Ordering it with the exhaust work means the sensor plugs back in cleanly instead of being left short or hard-wired in.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men handles exhaust fitting and the wiring that comes with it across the Illawarra. We can supply this loom alongside the exhaust job so the oxygen sensor reconnects properly once the new system is on. Listed to fit the VZ-VE V8 with the square plug; confirm your connector with us.
