The high-temperature Teflon wire and fiberglass loom allow the harness to be placed close to the exhaust manifolds without the worry of being damaged. The harness’s small 1/4″ outer diameter allows it to be routed in tight areas while providing increased clearance from hot or moving components (i.e. turbo systems). The loom’s black outer jacket provides for a low-key appearance in your engine compartment.
Racetronix oxygen sensor extensions allow for easy relocation of oxygen sensors. This is perfect for the installation of headers which require the oxygen sensor be moved further downstream.
