Lexus IS Catalytic Converter 2 (Ii) (2005-2013)

The Lexus IS catalytic converter is a key exhaust system component designed to reduce harmful emissions by converting toxic gases into less harmful substances. It helps the vehicle meet Euro 4 or EPA environmental standards, ensuring compliance and supporting cleaner air quality.

The catalytic converters are compatible with Lexus IS Xe20 models (GSE20, ALE20, USE20) from 2005 to 2011, including:

• 2.5L 4GR-FSE petrol engines (208 hp)
• IS250 (2006-2015) and IS350 (2006-2017 RWD) with 3.5L V6 engines

These converters may be positioned at the rear, before the left front axle, or integrated into the exhaust manifold on the driver or passenger side depending on the model.

Key specifications include:

• Positions: rear, front left axle, or integrated to exhaust manifold (bank 2 driver side RWD)
• Lengths range from 670 mm to 1960 mm
• Weight varies between 0.374 kg and 18.5 kg
• Materials: metal and ceramic substrates with stainless steel housing
• Connector type: 2 bolt flange with 1 O2 sensor port
• Emission standards compliance: Euro 2/3/4, EPA certified

These features ensure durability, proper fit, and high emission reduction efficiency.

Common signs indicating replacement include:

• Check engine light with fault codes such as P0420 or P0430 indicating catalyst efficiency below threshold (often for bank 2)
• Reduced engine performance or increased emissions
• Unusual exhaust smells or noises

It is essential to verify OBD diagnostics and choose compliant, direct-fit catalytic converters for proper legal and functional replacement.

Important factors for selection:

• Ensure OEM or high-quality aftermarket parts that comply with Euro 4 or EPA standards
• Check exact fitment for your vehicle's engine type, bank side, and model year
• Prefer direct-fit products with correct connectors and sensor ports
• Verify warranty and manufacturing quality—stainless steel bodies and ceramic substrates often provide best durability
• Avoid universal or non-certified converters to meet legal and performance requirements

Consult technical data and professional support if unsure about compatibility or installation.

Yes, these catalytic converters are designed to meet stringent emission standards:

• Euro 4 compliance for European vehicles
• EPA certification for vehicles in the United States
• ECE E24-103R approval for authentic European manufacturing standards
• Manufactured with high-quality metallic and ceramic substrates to ensure efficient pollutant reduction

Always confirm product certification and regulatory compliance before installation to ensure legal road use and environmental protection.

To maintain and replace your catalytic converter effectively, consider the following:

• Regularly check engine codes to detect catalyst efficiency issues early
• Use parts certified to meet local emission standards (e.g., EPA, Euro 4)
• Replace Lambda sensors along with the catalytic converter after 80,000–100,000 km
• Perform installation by trained professionals to ensure correct fit and function
• Avoid short trips that prevent the engine and exhaust system from reaching operating temperature, thus prolonging converter life

Proper care helps maintain engine performance, reduces harmful emissions, and ensures compliance with legal requirements.
