Jaguar XK Catalytic Converter

A catalytic converter for Jaguar XK is an essential exhaust system part that reduces harmful emissions from petrol V8 engines such as 3.2i, 4.0, and 4.2. These converters contain a monolith impregnated with precious metals that efficiently convert toxic gases into less harmful substances, ensuring your vehicle meets emission standards.

These catalytic converters fit various Jaguar XK models, notably:

• XK8 and XKR models from 1996 to 2014
• Jaguar XK8 Coupe 4.0 XKR with engine codes AJ27S or EC<AJV8>
• Jaguar XK 4.2i (2006-2014), matching OEM reference JMJ1091533
• XK8/XJ8 3.2i/4.0i from 1996 to 2003 (Euro 2 standard)
• Jaguar XK Coupe 4.2 XKR 416 CV (rear axle system)

Always verify your engine details and model year to ensure proper fitment.

There are mainly three types of catalytic converters for Jaguar XK:

• OEM-quality new catalytic converters: Made to original specifications, stainless steel construction, fully compliant with regulations.
• Replacement catalytic converters: Designed to match or exceed OEM standards for emissions and durability.
• Sport catalytic converters: With enhanced flow characteristics and improved sound while maintaining emission compliance (e.g., 200/300 CPSI cells, EU6 compliant).

Choose the type based on your vehicle's needs, local emission laws, and desired performance characteristics.

Common signs that your catalytic converter may require replacing include:

• Illuminated check engine light relating to emissions
• Reduced engine performance or power
• Unusual exhaust smells or noises

• Check for certified approval (e.g., TÜV SÜD, E24-103R) guaranteeing compliance and performance
• Consider OEM or equivalent quality parts to maintain vehicle conformity and warranty coverage
• Look for installation support and technical documentation to ensure proper fitment

Proper selection will maintain your Jaguar’s performance, emission compliance, and longevity.
