Wiring Specialties Oxygen Sensor Extension Harnesses

4.65 out of 5 stars 17 Customer Reviews

Wiring Specialties oxygen sensor extension harnesses make it simple to lengthen your O2 sensor wiring harness. Modifications like long tube headers or turbo kit upgrades could mean your O2 harness will be too short. Wiring Specialties has a safe, reliable solution with these easy-to-install extensions. High temperature adhesive tubing seals connections against moisture and heat. Wiring Specialties uses Hilec fireproof fiberglass sleeve to protect against high heat applications. Choose the plug style needed for your vehicle application.
