This ISR Performance O2 harness extension is made for early VQ35DE Nissan 350Z models to extend oxygen sensor wiring for custom exhaust or turbo installations. The extension preserves sensor placement options during fabrication or engine swaps, allowing installers to route O2 wiring without relying on splicing factory leads, and simplifies modifications that change exhaust or sensor locations.
