The 2006 Infiniti G35 comes equipped with Nissan’s VQ35DE 3.5-liter naturally aspirated V6 engine. This aluminum DOHC engine produces 280 horsepower at 6,200 RPM and 270 lb-ft of torque at 4,800 RPM in the sedan, while coupe models produce slightly higher numbers at 298 horsepower. The VQ35DE features variable valve timing on the intake side and has a compression ratio of 10.3:1. This engine is known for its smooth power delivery and distinctive exhaust note, making it a popular choice among enthusiasts. The VQ35DE requires premium fuel for optimal performance and has a reputation for being relatively reliable when properly maintained with regular oil changes every 3,750 miles.

The 2006 Infiniti G35 shares most parts with other first-generation G35 models from 2003-2007, though there are some important distinctions. Engine components from the VQ35DE are largely interchangeable across all years, including intake manifolds, valve covers, and internal engine parts. However, 2005-2006 models received updated suspension components and brake systems that differ from earlier years. Body panels and interior components are generally compatible across the entire 2003-2007 range, with minor trim variations. The 2007 model year introduced the VQ35HR engine in some configurations, so engine-specific parts from 2007 may not be compatible. Transmission parts vary between manual and automatic variants but are consistent within each transmission type across the generation. Always verify part numbers when sourcing components, as running changes occurred throughout production.

The VQ35DE 3.5L V6 in the 2006 Infiniti G35 is generally considered a reliable and durable engine when properly maintained. Most examples can easily exceed 200,000 miles with regular maintenance, particularly consistent oil changes every 3,750 miles using quality oil. The engine’s main weakness is the valve cover gaskets, which commonly leak after 80,000 miles, but this is more of a maintenance item than a catastrophic failure. The timing chain system is robust and doesn’t require replacement like timing belts, though the chain tensioners may need attention at very high mileages. Regular maintenance should include spark plug replacement every 60,000 miles and coolant system service. The engine responds well to premium fuel and benefits from occasional high-RPM driving to keep carbon deposits at bay. Overall, it’s one of Nissan’s better engines from this era.
