This Muzzys o2 sensor extension was manufactured using high temperature cross-linked polyethylene TXL wire & OEM Delphi-Packard connectors, pins and seals to ensure a secure, long lasting, moisture free connection. These are the same components used on the factory harness.
Oxygen sensor extensions for upstream (closest to motor) O2's. The harnesses are 24" long. .
When you install most aftermarket headers, it moves the oxygen sensor bungs towards the rear of the car, farther from the factory harness, so extensions are required. These extensions make the installation hassle free by not having to cut and splice the factory wiring.
