Land Rover Part Number: WCD500202 - Catalytic Converter
WCD500202 is a catalytic converter fitted to the exhaust system of vehicles with the 4.4 AJ Petrol V8 engine. The unit contains a honeycomb ceramic monolith coated with catalytic materials that convert carbon monoxide, unburned hydrocarbons and nitrogen oxides into less harmful compounds. Positioned downstream of the engine and matched to the exhaust routing and mounting points for the applicable models, the converter maintains emissions within regulatory limits and helps preserve exhaust performance; a damaged or blocked converter can increase backpressure, reduce engine performance and raise emission readings. Replacement must match the exact part number and fitment to avoid exhaust leaks or incorrect backpressure characteristics.
