SPDZ1 Oxygen Sensor Extension Harnesses are engineered to provide a high quality, reliable solution when additional sensor harness length is required—especially during header or exhaust upgrades that relocate factory oxygen sensors downstream.
Designed with OEM-style connectors and high-quality wiring, these extensions ensure proper sensor function without cutting, splicing, or modifying your factory harness. The result is a plug-and-play installation that maintains signal integrity, prevents wiring strain, and helps keep your engine management system operating as intended.
Whether you’re installing long-tube headers or custom exhaust components, SPDZ1 delivers the durability and fitment you expect from performance-driven hardware.
Key Features
Plug-and-play design with factory-style connectors
Allows safe relocation of oxygen sensors during header or exhaust installs
High-temperature, automotive-grade wiring for long-term reliability
Prevents harness tension and potential sensor damage
