The Redback PEXJIMNY is an oxygen (O2) sensor wiring loom extension listed to fit the Suzuki Jimny. It isn't an exhaust in its own right — it's the small wiring part that lets the factory O2 sensor reach its plug once an extractor or header change moves the sensor's position.

What is an O2 sensor loom extension and why fit one?

When you fit extractors or a new header to a Jimny, the oxygen sensor can end up further from its original connector than the factory loom allows. An O2 sensor wiring loom extension bridges that gap so the sensor plugs back in without stretching, splicing or modifying the standard harness. It's a supporting part rather than a power or sound upgrade — its whole job is to keep the engine's fuelling feedback connected and the dash sensor reading correctly after the manifold work.

Will it suit my Suzuki Jimny?

It's listed to fit the Suzuki Jimny. Because looms differ by build and by which extractor or header you're running, the right extension depends on where your O2 sensor ends up; send your Jimny's details and we'll confirm this is the correct loom for your setup before ordering.

Is it road legal?

This is a wiring extension, not an emissions component — it keeps the factory oxygen sensor connected rather than removing or altering it. Road compliance is governed by the exhaust and emissions hardware on the vehicle, so confirm the overall setup and any state requirements with the workshop.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men can supply this Redback loom extension and fit it alongside Jimny extractor or header work across the Illawarra. It's a small part of a larger job, so we typically check it against your sensor location when the manifold goes on. The recommended retail is $129.99, which we confirm with you, along with availability, before ordering.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

What does the PEXJIMNY actually do?
It extends the factory oxygen sensor's wiring so the sensor still reaches its plug after extractor or header work on a Suzuki Jimny. It doesn't change power or sound.
Do I need it with new extractors?
Often, yes — if the new manifold moves the O2 sensor away from its original connector. Send your Jimny build to the workshop and we'll confirm whether this loom is the right one for your setup.
