Wideband Extension Harness To suit LSU4.9 Length: 1.2M (4ft)

This Haltech wideband extension harness provides an additional 1.2 metres of cable length for LSU4.9 oxygen sensors, offering greater flexibility in sensor placement and routing. Purpose-engineered with proper shielding and connector terminals, it maintains signal integrity for accurate air-fuel ratio monitoring during dyno tuning and real-world operation. The four-foot extension is particularly useful when mounting wideband sensors further downstream or accommodating custom exhaust configurations where standard harness length proves restrictive. Essential for professional tuners requiring precise AFR data without signal degradation or interference.
