Both products serve different purposes, and the right choice depends on your situation.

The Catalytic Converter Cleaner helps reduce carbon buildup inside your fuel system and catalytic converter, making it a great first step if your vehicle is experiencing reduced efficiency or early-stage issues.

The O2 Sensor Adapter (Spacer) works externally by adjusting the position of the downstream oxygen sensor, which can help reduce inaccurate readings that may trigger check engine light codes.

👉 In simple terms:

• Cleaner = supports internal cleaning and performance
  
• Adapter = helps manage sensor readings
  

If you're unsure, starting with the cleaner is recommended. For vehicles with persistent or recurring issues, many customers choose to use both together for a more complete approach.
