Toyota Prius Catalytic Converter 2 (Ii) (2003-2009)

The Toyota Prius 2 catalytic converter is a crucial part of the vehicle's exhaust system, designed to reduce harmful emissions. It complies with Euro 4 and Euro 5 standards mainly and is built for the 2003-2009 Prius 2nd generation with the 1.5L 1NZ-FXE hybrid engine. This component helps the Prius run cleaner by converting toxic gases into less harmful substances, helping protect the environment.

Key specifications for the Toyota Prius 2 catalytic converter include:

• Engine code: 1NZ-FXE
• Power output: 112 HP (82 kW) or 78 HP (58 kW)
• Emission standards: Euro 4, Euro 5 compliant, with OBD compatibility
• Size: typically 2070 mm length (some models 2135 mm or 340 mm universal fit)
• Weight: 9 to 10 kg depending on model
• Position: center or front of exhaust system
• OE Toyota reference number: 17410-21490
• Suitable for Prius 2 1.5 Hybrid NHW20 from 2003 to 2009

Yes, there are both direct-fit and universal catalytic converter models available for the Prius 2:

• Direct-fit converters match original dimensions and mounting points for easy installation.
• Universal converters come in shorter lengths but can be adjusted to fit with additional work.
• All replacements should be Euro emission compliant and compatible with OBD systems to avoid engine or inspection issues.

Always verify compatibility with your car's engine code and emissions specifications.

Yes, Prius catalytic converters are often targeted for theft due to precious metals inside. Protection options include:

• Steel protection plates, typically 2 mm thick, designed to shield the converter from theft attempts.
• Security kits combining the catalytic converter and shield for enhanced defense.

These anti-theft shields are designed to not interfere with maintenance tasks like oil or transmission fluid changes and do not cause overheating of the catalytic converter.

When replacing a stolen catalytic converter in California, consider these points:

• Ensure the replacement catalytic converter is CARB/EPA compliant to meet California emissions laws.
• OEM or certified aftermarket catalytic converters are recommended to avoid engine error codes and inspection failures.
• Magnaflow is a known alternative brand; however, verify it meets local emission compliance and fits your Prius 2.
• Shipping options vary; some sellers offer fast shipping or even free shipping promotions.
• Check return policies and warranty coverage, typically a 3-year warranty is standard.

The catalytic converter processes engine exhaust gases by catalyzing chemical reactions that convert harmful pollutants into less harmful emissions before they exit the tailpipe. Key elements of its function include:

• Oxidizing carbon monoxide (CO) into carbon dioxide (CO2)
• Converting unburned hydrocarbons (HC) into water (H2O) and CO2
• Reducing nitrogen oxides (NOx) into nitrogen (N2) and oxygen (O2)

This reduces the vehicle's environmental impact and helps the Prius meet stringent emission standards.

Anti-theft shields designed for the Prius catalytic converter are specifically made to not interfere with routine maintenance such as engine oil changes or transmission fluid servicing. They:

• Allow access to necessary maintenance points without removal in most cases
• Are engineered to prevent overheating of the catalytic converter
• Include mounting hardware and instructions for proper installation

It is advisable to follow manufacturer guidance and consult with a mechanic for installation and maintenance questions.

You can purchase high-quality replacement catalytic converters for the Toyota Prius 2 directly from reputable manufacturers that provide:
