Toyota Previa Catalytic Converter 2 (Ii) (2000-2005)

The Toyota Previa Catalytic Converter 2 is compatible with Toyota Previa models from 1994 to 1997 equipped with the 2.4L 4-cylinder engines, specifically engine codes 2TZ-FE and 2TZ-FZE. It fits non-supercharged and supercharged variants within these years. For reference, the first generation Previa (1990-1994) utilizes a catalytic converter approximately 925 mm long and weighing about 5 kg, while the catalytic converters for the second generation (2000-2005) weigh around 7.7 kg.

There are two main types of catalytic converters for the Toyota Previa:

• Non-supercharged models (1991-1995): Made with stainless steel construction and a ceramic substrate.
• Supercharged models (1994-1997): Feature an oval stainless steel body with two oxygen sensor ports flanged for proper fitment.

Modern versions use a honeycomb structure, which replaces older ceramic bead substrates, enhancing exhaust flow performance and reducing backpressure.

The catalytic converter in the Toyota Previa functions by converting harmful exhaust gases into less polluting substances through chemical reactions. This process includes:

• Carbon monoxide (CO) to carbon dioxide (CO₂)
• Hydrocarbons (HC) into water (H₂O) and carbon dioxide (CO₂)
• Nitrogen oxides (NOx) into nitrogen (N₂)

To achieve these reactions efficiently, Toyota catalytic converters use precious metals such as platinum, palladium, and rhodium embedded in the catalyst substrate.

The primary OEM part number for the Toyota Previa Catalytic Converter 2 is 18450-76120. Additional compatible reference codes include:

• TCR10L-REMDKA
• TCR10L-REMDKK
• TCR10L-RESDKA
• TCR10L-RESDKK
• TCR10L-RESDVA
• TCR10L-RESDVK

These part numbers help ensure you select the correct converter for your vehicle model and engine type.

Toyota Previa catalytic converters, especially those for non-supercharged models (1991-1995), are available with California Air Resources Board (CARB) certification guaranteeing compliance with strict environmental regulations. Certified converters typically include an installation kit and meet federal and California EPA emissions standards, ensuring proper emission control and legal compliance for your vehicle.

Replacement catalytic converters for the Toyota Previa are offered by various reputable manufacturers with quality warranties:

• Walker: Provides a 25,000 miles (40,000 km) emissions warranty and a 5 years (50,000 miles) structural warranty.
• MagnaFlow: Offers multiple options including street/touring and competition/sport grade catalytic converters.
• OEM Toyota Parts: Carry full factory original warranties ensuring high-quality and proper fitment.

Select a brand and warranty rated to your vehicle's emission and performance requirements.

Catalytic converters are valuable due to their core components made from precious metals, including platinum, palladium, and rhodium. These materials catalyze the chemical reactions required to convert toxic exhaust emissions into less harmful gases, making catalytic converters essential for vehicle emission control while being costly to produce and replace.

The cost of a Toyota Previa catalytic converter varies depending on the brand, certification, and converter grade. Prices typically reflect the materials used and quality standards, including CARB or EPA compliance. Installation may require professional service with the correct gaskets, sensors, and fittings. Detailed installation manuals and technical support are available from specialized suppliers and professional service providers to ensure proper fit and function.

Many suppliers offer online catalogs, vehicle fitment search tools, and delivery options to facilitate your purchase and installation process.
