Oxy Sensor Restrictor 90 Degree TB48 VK56 - Nissan Patrol Y61 GU & Y62

Oxy Sensor Restrictor 90 Degree - Nissan Patrol Y62 VK56 & GU Y61 TB48

This 90-degree oxygen sensor restrictor is designed to be fitted into the exhaust system bung for the post-catalytic converter (downstream) oxygen sensor. The oxygen sensor is then screwed into this restrictor, effectively spacing it out from the direct flow of exhaust gases.

This component is commonly required when fitting aftermarket high-flow catalytic converters or de-cat pipes. These modifications can alter the exhaust gas readings, causing the vehicle's ECU to detect a fault with catalyst efficiency and trigger a Check Engine Light (CEL), typically with the fault code P0420. This restrictor helps to normalise the readings seen by the sensor, preventing the CEL from illuminating and ensuring the engine runs as intended.

These are used to Mimic a Catalytic convertor, so that the Oxygen sensor doesn't cause engine malfunction lights.

These can be used if you have replaced your Headers or Cats with High Flow versions

Note: * These are for Offroad Use only Product Features

• Eliminates Check Engine Lights: Specifically designed to resolve CEL and DTC fault codes like P0420 (Catalyst System Efficiency Below Threshold) after exhaust modifications.
• 90-Degree Angled Design: Ideal for installations in tight or hard-to-reach areas where a straight spacer will not fit.
• Durable Construction: Manufactured from high-grade steel for excellent durability and resistance to high temperatures and exhaust corrosion.
• Simple Installation: A direct screw-in solution with no modification required, making it a quick and easy fix.
• Universal M18x1.5 Thread: Fits most standard oxygen sensors, ensuring a secure, leak-free connection.
