Lexus RX Catalytic Converter 2 (Ii) (2003-2009)

The Lexus RX Catalytic Converter 2, often referring to the catalytic converter on Bank 2 for V6 engines, is a vital component of the exhaust system. It reduces harmful emissions by converting hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful gases through a three-way catalytic converter that combines oxidation and reduction reactions. It operates optimally with an air/fuel ratio of 14.7:1 monitored by upstream and downstream oxygen sensors.

Catalytic Converter 2 fits specific Lexus RX models and years depending on engine type and position. Key examples include:

• 2007 RX350 with 3.3L 6-cylinder engine
• 2007–2009 RX350 with 3.5L V6 center pipe
• 2010–2015 RX350 3.5L V6 front pipe
• 2016–2022 RX450h 3.5L V6, Bank 2 side
• 2020–2025 RX350 various engines and positions including 2.4L 4-cylinder

Always check exact compatibility by VIN or manufacturer part number before purchase or installation.

The catalytic converter functions by storing and processing oxygen within a ceramic or metallic monolith coated with precious metals to oxidize HC and CO and reduce NOx emissions. It depends on a precise air/fuel mixture and oxygen sensor feedback for optimal performance.

• Common issues include clogging, poisoning, or air/fuel ratio imbalance.
• Oxygen sensors detect malfunction by monitoring exhaust gases upstream and downstream.
• Professional tools are required to diagnose problems and test converter efficiency.
• Faulty converters trigger diagnostic trouble codes (DTC) and illuminate the Malfunction Indicator Lamp (MIL).

Replacement procedures vary according to engine type and model year, and some parts are integrated with the exhaust manifold.

Yes, there are high-quality direct-fit aftermarket catalytic converters designed for Lexus RX models, including:

• High-purity coatings ensuring over 99% reduction of CO and NOx, and 97%+ for HC emissions.
• Converters designed to resist catalyst poisoning and ensure long-term durability.
• For RX450h Bank 2 (2016–2022), aftermarket replacements that are OBDII compliant and fit without cutting or welding.

Always confirm aftermarket parts meet emissions compliance such as CARB or EPA to avoid check engine defaults.

OEM Lexus catalytic converters are generally covered by the factory warranty. For products from trusted suppliers like Krosfou, the warranty details include:

• 3-year warranty limited to 100,000 kilometers of use.
• Warranty commencement upon date of product receipt.
• Coverage requires installation by qualified professionals and adherence to specified installation and maintenance recommendations.
• Warranty covers manufacturing defects but excludes damage from misuse, negligence, or clogging.

Always keep invoices and technical support forms ready for warranty claims.

Key installation and maintenance tips include:

• Allow the exhaust system to cool down fully before replacing the catalytic converter.
• Replace oxygen sensors simultaneously if old or faulty to ensure proper readings.
• Use only copper connections when installing additional connections in front of the catalytic converter.
• Follow the original manufacturer's torque specifications and procedures.
• Ensure the catalytic converter matches the engine displacement and emission standards of the vehicle.
• Avoid frequent short trips that prevent the engine from reaching operating temperature, as this can reduce catalytic converter lifespan.

Proper installation and use prolong converter life and maintain vehicle emissions compliance.

Genuine parts can be sourced from authorized Lexus parts suppliers and trusted manufacturers like Krosfou. Additional support includes:

• VIN-based part compatibility confirmation.
• Technical manuals and installation guides available upon request.
