Lexus LC 500/500h Catalytic Converter Malaysia
LC 500 V8 has 4 cats. LC 500h V6 has 2. Very durable — failure before 150,000 km is uncommon if oil consumption is managed. OEM replacement: (V8). Any P0420/P0430 code on a high-mileage LC 500 should prompt an oil consumption investigation first.

Lexus LC Catalytic Converter
- LC 500 uses 2UR-GSE V8 naturally aspirated — four catalytic converters (two per bank); LC 500h uses 3.5L V6 hybrid with two cats; both meet Euro 6 emission standards
- LC V8 cat lifespan: high-revving naturally aspirated V8 running premium fuel — catalytic converters designed for 200,000+ km; failures are rare outside of oil consumption issues
- LC cat service: as flagship LC is low volume in Malaysia — sourcing OEM cats may require advance order from Lexus dealer; aftermarket cats for LC are very limited
- LC low-stance cat access: LC sits very low — any exhaust or cat work requires full lift; inspect cat heat shields and rubber exhaust mounts at each major service
