The extension cable is fully compatible with the original front oxygen sensor systems of these sports cars, matching the factory pin configuration and wiring specifications to ensure stable electrical signal transmissionno rewiring or modification is needed for seamless integration with the vehicles engine control unit.
Crafted with high-quality copper wires and heat-resistant insulation, the cable can withstand high temperatures under the vehicles hood, resisting corrosion, abrasion, and damage from exhaust heat or road debris. The precision-molded 8-pin connectors ensure a tight, secure fit with the original sensor and vehicle harness, preventing loose connections that could cause inaccurate fuel-air ratio readings, check engine light activation, or reduced engine performance. The 24-inch length provides ample extra wiring to relocate the oxygen sensor during exhaust manifold replacement, header installation, or other under-hood modifications, while the durable construction guarantees long-lasting reliability even in harsh driving conditions
