Product Description

Oxygen Sensor Bung Adapter CEL Eliminator

Mini Catalytic Converter Inside: Designed for Stainless Steel 304 mini catalyst O2 Oxygen Sensor Lambda Extender Spacer M18X1.5 with E3 standards.

In vehicles compliant with EURO 3 and higher emission standards, the second lambda oxygen sensor emulator is positioned after the catalytic converter for diagnostic purposes. If irregularities are detected based on the engine control unit data, a "CHECK ENGINE" error appears on the dashboard, potentially switching the engine into emergency mode and causing a significant power drop.

These issues commonly arise during catalyst removal, low catalyst efficiency, or replacement with a jet pump. In such cases, installing the Second Lambda Oxygen Sensor Extender becomes essential. This solution can help restore performance, as the catalyst can reduce power output by 2% to 3% and maximum power speed by up to 5%.

  • Cost-effective way to raise power after catalyst removal.
  • Solves "CHECK ENGINE" light issues related to LPG installations detecting rich mixtures.
  • Ensures smooth engine operation without emergency mode triggers.

Frequently Asked Questions
What is the main function of the CEL Eliminator?
It is designed to eliminate the "Check Engine Light" (CEL) that often appears after removing the catalytic converter or installing a high-flow exhaust. It mimics the presence of a functional catalyst for the secondary oxygen sensor.
Will this adapter fit my car?
This adapter features a standard M18x1.5 thread, which is universal for most modern vehicle oxygen sensors. It is suitable for most cars with Euro 3 or higher emission standards.
Does this adapter contain a real catalytic converter?
Yes, it features a built-in mini catalytic converter (ternary catalysis) inside, which helps filter the exhaust gases reaching the sensor to provide a correct reading to the ECU.
What material is the adapter made of?
The adapter is constructed from high-quality Stainless Steel 304, ensuring excellent durability, heat resistance, and corrosion protection.
Is professional installation required?
While it is a straightforward bolt-on installation, we recommend professional installation to ensure proper fitment and to avoid damaging the delicate oxygen sensor threads.
Can this adapter improve engine performance?
By preventing the engine from entering "emergency mode" or "limp mode" due to catalyst errors, it helps maintain full power output and optimal throttle response.
