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

Prices depend on the vehicle model and required certification. Here's a breakdown:

At Krosfou, you're buying straight from the manufacturer, so you get the best value without sacrificing quality.

Because of the hybrid powertrain, Prius converters need more precious metals to function efficiently under lower heat conditions. This makes them both more durable and more desirable for illegal resale. Still, our approved alternatives meet the same standards and come at a much lower cost.

Older vehicles — especially the Gen 2 and Gen 3 models — are commonly targeted. Their exposed layouts make them easy to steal from, particularly when left in public spaces without extra guard protection.

You'll likely notice:

• A sharp increase in engine sound
• Drop in fuel efficiency
• A check engine warning or sensor alert
• Missing or hanging exhaust pipe under the car

If you experience these signs, don't drive — your EGR system and manifold may be exposed.

Here are a few proven tips:

• Install a shield or security plate
• Park in a secure garage or monitored area
• Use visible deterrents like warning stickers or etching systems
• Register your converter details in a traceable database

Our parts fit Toyota Prius models with security-focused enhancements and particulate protection built in.

Absolutely. A strong plate or metal guard deters criminals by making access more difficult and time-consuming. These are essential for Prius owners in high-risk areas — and we offer several options that are easy to install and affordable.

Right here in our online shop. We stock:

• Type-approved parts for every generation Prius
• Kits sold with gaskets, plates, and brackets
• Safe checkout, warranty, and fast delivery options across Europe

If you're comfortable working under the vehicle, installation is possible at home. We even provide video guides and a full installation process walkthrough.

But if you're unsure, we always recommend professional service at your nearest auto center, especially for pipe alignment or sensor calibration.

Follow these steps:

• Match your engine code (1NZ-FXE, 2ZR-FXE, etc.)
• Confirm Euro compliance level
• Use our site's search and filter tools by category, variant, and chassis code

This ensures you get the right fit and avoid installation headaches.

A type-approved part is officially certified to meet European emission standards. It's your guarantee of safety, legality, and proper performance. All our stock meets these strict EEC regulations.

Sometimes, yes. If your unit is clogged (but not damaged), you can try:

• Special cleaning additives
• Vapour or hydrogen flushes
• An ultrasonic process from a qualified garage

However, if the problem is more than just build-up, you'll need to replace it.

Most kits include:

• Gaskets
• Mounting hardware
• Optional heat plates, sensors, or pipe sections

Be sure to check the condition of reused parts, especially if you've had a stolen catalytic or a failed emission test.

No — doing so may cause:

• Failed MOT/emissions inspections
• Faulty readings from the core sensors
• Legal and environmental risks

Replace the unit as soon as possible to stay road-legal and avoid damaging the EGR or fuel system.

OEMs from Toyota, Klarius are solid choices — but come with a high price tag. Our approved aftermarket parts offer original-like performance, long lifespan, and lower cost per km. Great option if you're buying on a budget.

No stress. Just contact us with:

• Your VIN or reg number
• Fuel type (petrol or diesel)
• Model year and body style

We'll help you find the exact fit — even if you're driving a lesser-known variant like the Prius C or Auris Touring Sports.

The Prius Prime and late Gen 4 models have better protection — their converters are mounted deeper within the underfloor assembly, making them tougher to access. Still, theft can happen. A deterrent plate is always a smart add-on.

Our conversion kits include:

• A new, genuine-quality converter
• All necessary fasteners, seals, and hangers
• Add-on options like pipes, deflectors, and sensor upgrades

Everything comes boxed and ready for your garage or home install.

Fast. We offer:

• 1–3 day shipping to most European locations
• Live tracking
• Simple checkout and basket management
• Support in your language, with helpful buying advice

Reach out to our team for:

• Help selecting the right converter for Toyota Prius
