Review INFINITI Engine 4.5l Vin 4th Digit Fits fits M45 2006–2007

The M45 engine boasts a displacement of 4.5 liters and features a double overhead camshaft design. It comprises 32 valves and 8 cylinders, arranged in a V-configuration for optimal power delivery and smooth operation.

The engine also utilizes Infiniti's Variable Valve Event & Lift (VVEL) system, which combines variable valve timing and variable valve lift for maximum power and efficiency.

One of the most striking aspects of the M45 engine is its output. It generates 330 horsepower at 6,800 rpm and 343 lb-ft of torque at 4,800 rpm. This power is routed to the wheels through a 5-speed automatic transmission, which offers seamless shifts and quick response times.

It features a cast-iron cylinder block, forged crankshaft, and forged connecting rods, ensuring that it can withstand the rigors of daily driving. Additionally, the engine's oiling system is designed to provide optimal lubrication, reducing wear and tear on internal components.

In summary, the Infiniti 4.5L V8 M45 engine, model 10374A, is an impressive powerplant that delivers ample power, advanced technology, and reliable performance.
