When it comes to keeping your car running great, INFINITI USA knows you want the best. The M45 represents INFINITI's flagship luxury sedan heritage, featuring a powerful V8 engine and sophisticated systems that demand premium maintenance and genuine parts. This full-size sedan combines executive-level comfort with impressive performance capabilities that require specialized knowledge and quality components for proper service. The M45's advanced engineering and luxury appointments make authentic INFINITI parts essential for maintaining its refined operation and reliability.
V8 Engine Performance and Maintenance
The M45's 4.5-liter V8 engine produces substantial horsepower while maintaining smooth operation through precise engineering that requires quality oil and filters for protection. Regular maintenance intervals become critical with high-performance engines, as delayed service can result in expensive internal damage or reduced performance output. Timing belts and related components in V8 engines require replacement at specific mileage intervals to prevent catastrophic failure that could destroy internal engine components.
Advanced Suspension and Handling Systems
The M45's sophisticated suspension system uses electronic controls and premium components to deliver both comfort and handling performance appropriate for a luxury flagship sedan. Steering systems in full-size sedans experience greater stress from vehicle weight and require periodic fluid changes and component inspection for continued precision. Brake systems designed for the M45's weight and performance capabilities need high-quality components that provide consistent stopping power under all conditions.
Luxury Features and Electronic Systems
Multiple electronic systems in the M45 cabin provide convenience and comfort features that depend on reliable electrical power and clean connections for proper operation. Climate control systems in luxury vehicles feature multiple zones and advanced filtration that require regular maintenance to preserve air quality and system efficiency. Alternators in vehicles with extensive electronic systems work harder and may require earlier replacement than those in simpler vehicles to maintain charging system reliability.
