ISR Performance Nissan 350Z (Early VQ35DE) O2 Harness Extension

If you're swapping your exhaust on an early Nissan 350Z with the VQ35DE engine, you'll likely run into a situation where your factory O2 sensor wiring isn't long enough to reach the new sensor location. This O2 harness extension from ISR Performance is designed to solve that exact problem, making your exhaust installation much smoother.

This extension is well-built with durable connectors that plug directly into your factory O2 sensor harness and the O2 sensor itself. It's a simple plug-and-play solution that avoids the need for cutting and splicing wires, which can sometimes lead to electrical issues down the road. The wiring is routed to give you just enough extra length to properly position your O2 sensor without creating excess slack that could get snagged or damaged.

Having the correct length harness extension ensures your O2 sensor can accurately read exhaust gases, which is crucial for your engine's computer to manage fuel mixture and emissions. This part is a popular choice for 350Z owners performing exhaust modifications.
