Say Goodbye to CEL, SES, and MIL Warnings!

Check engine light

Is your dashboard lighting up with a Check Engine Light (CEL), Service Engine Soon (SES), or Malfunction Indicator Light (MIL)? Have you recently installed modifications like a test pipe, high-flow catalytic converter, catless exhaust, or a performance exhaust system? If so, our cutting-edge O2 Sensor Spacer is the solution you’ve been looking for!

​​
What is the O2 Sensor Spacer?
The O2 Sensor Spacer is an advanced oxygen sensor adapter designed to eliminate common fault codes like P0420 and P0430. Equipped with a built-in miniature catalytic converter, it addresses the challenges faced by high-performance and modified vehicles, helping maintain optimal engine function, reduce emissions, and unlock added horsepower.
​
Why Choose Our O2 Sensor Spacer?

  • Integrated Mini Catalytic Converter: Contains a 400-cell ceramic core treated with platinum, palladium, and rhodium, which catalyze harmful exhaust gases into harmless substances.

  • Universal Fit: Compatible with all vehicles using M18 x 1.5mm oxygen sensor ports. 

  • Durability: Made from T-304 stainless steel, resistant to corrosion and heat up to 620°C, ensuring long-term reliability under extreme conditions.

  • Wide Application: Perfect for high-flow catalytic converters, turbocharged setups, non-turbocharged vehicles, catless systems, and more.

​
How It Works
Modifying your vehicle’s exhaust system can lead to incorrect readings from the rear oxygen sensor, which monitors post-combustion emissions. This sensor can trigger error codes when exhaust gases exceed factory limits, often causing the ECU to enter limp mode.
Our O2 Sensor Spacer tackles this by:

  1. Adjusting the position of the oxygen sensor to reduce direct exposure to exhaust flow.

  2. Simulating the presence of a fully functional catalytic converter with its integrated mini catalytic element.

  3. Helping the ECU read balanced exhaust levels, preventing error codes and restoring full engine performance.

​
Simple Installation
Installing the O2 Sensor Spacer is quick and straightforward. Just attach it to the rear oxygen sensor and screw it into the O2 sensor port—no welding or electrical modifications needed. Most installations take under 10 minutes, and it can be easily removed if necessary.
​
Materials & Performance
The O2 Sensor Spacer is crafted from T-304 stainless steel, renowned for its resistance to rust, peeling, and high temperatures. Unlike inferior galvanized carbon steel that can degrade under heat and contaminate the exhaust system, our product withstands the harshest conditions to deliver consistent results. The built-in catalytic honeycomb remains stable at high temperatures, effectively converting exhaust gases into harmless emissions.
Disclaimer
While our O2 Sensor Spacer resolves CEL issues in most cases, occasional instances may arise where sensor sensitivity or ECU configurations still trigger fault codes. Results can vary depending on vehicle modifications and ECU tuning.
