Lexus LX 570 Catalytic Converter Replacement Malaysia
LX 570 V8 has 4 catalytic converters. Port injection keeps cat health excellent — failure is very rare before 200,000 km. OEM replacement set. Theft risk: large trucks and luxury SUVs in Malaysia are increasingly targeted — consider a catalytic converter anti-theft shield.
Lexus LX Catalytic Converter
- LX 570 uses 3UR-FE V8 (same as Land Cruiser 200) — four catalytic converters total (two per bank in dual exhaust); large engine produces more exhaust mass requiring larger cat volume
- LX cat lifespan: V8 naturally aspirated running premium fuel — cats typically last 200,000+ km; most failures are P0420/P0430 from aged O2 sensors rather than true cat failure
- LX P0420 diagnosis: always check upstream O2 sensor heater circuit first — LX O2 sensors are expensive; a failed O2 heater causes false catalyst efficiency codes
- LX cat replacement cost: V8 with four converters — replacing all simultaneously is the correct approach if high mileage; mixing new and old cats causes diagnostic confusion
