Why You'll Love This O2 Sensor Spacer
- Precision machining: Hexagonal base and stepped profile ensure rock-solid fitment into your exhaust pipe without wobble or misalignment.
- Durable stainless construction: Brushed metallic finish resists corrosion and thermal stress, built to outlast typical sensor extensions in high-heat exhaust environments.
- Integrated mesh filter: The engineered filter element works as a catalytic converter sensor adapter, helping manage exhaust flow while protecting sensor integrity on deleted or modified systems.
- Dual-threaded design: Internal female threads accept your oxygen sensor; external male threads screw directly into the exhaust pipe for seamless installation as a 90 degree 02 sensor spacer or straight adapter.
- Versatile compatibility: Works as a spacer for 02 sensor applications, exhaust sensor spacer solutions, and catalytic converter sensor adapter setups on street, off-road, and tuned vehicles.
