❓Why Does the Check Engine Light (CEL) Come On?

⚠️ Common causes of CEL activation:▫️ Catalytic Converter Issues – Reduced efficiency (e.g., P0420 code) is a frequent trigger.▫️ O2 Sensor Problems – Over-sensitive or faulty sensors may cause false alarms or persistent lighting.💡 Key Note: This product is a front-mounted mini catalytic converter designed to specifically address tailpipe emission issues caused by a failed catalytic converter, reducing toxic gas emissions. It does NOT solve all CEL problems (e.g., sensor malfunctions may still trigger lights or additional error codes after installation).

Core Functionality

🚗 True Catalytic Core – No Useless ExtensionsUnlike ordinary extension pipes, features an integrated micro catalytic unit that mimics OEM catalytic converter logic:▫️ Fools ECU System: When the original catalytic converter is removed, the rear O2 sensor detects high-temperature unburned fuel, triggering P0420/P0430 codes. This spacer optimizes exhaust data via catalytic reaction to bypass ECU detection.▫️ Off-Road Use Only: Suitable for non-road scenarios (e.g., race tracks, off-road vehicles). ILLEGAL FOR ROAD VEHICLE MODIFICATIONS!

📦 Package Includes

🔍 Contents: 1 x O2 Sensor CEL Eliminator (with catalytic function)⚠️ Important Notes:▫️ Manual Measurement Tolerance: 1-3mm size deviation may occur – confirm compatibility before ordering.▫️ Display Color Variation: Slight color differences may exist due to monitor settings; refer to physical products.

💡 Usage Tips

✔️ Prioritize Code Diagnosis: Use an OBD scanner to identify the root cause (choose this product for catalytic converter-related issues).❌ Not a Universal Solution: If the CEL is due to sensor damage or electrical problems, other components must be repaired simultaneously.

WARNING: This is an off-road modification part not approved for road vehicle emission compliance. Always adhere to local laws and regulations!
