The 2004 Infiniti G35 is equipped with Nissan’s VQ35DE 3.5-liter naturally aspirated V6 engine. This aluminum DOHC engine produces 260 horsepower at 6,000 RPM and 260 lb-ft of torque at 4,800 RPM in the sedan, while the coupe version makes 280 horsepower. The VQ35DE features variable valve timing on the intake side and is known for its smooth power delivery and distinctive exhaust note. It’s paired with either a 5-speed automatic transmission or a 6-speed manual transmission depending on the trim level and body style chosen.

The 2004 Infiniti G35 shares most parts with the 2003-2006 G35 models, as they’re part of the same first-generation V35 platform. The VQ35DE engine components are largely interchangeable across these years, though there were minor updates in 2005 and 2006. Body panels and interior components from 2003-2006 sedans are generally compatible, while coupe parts fit 2003-2007 coupes. Some electrical components and ECU modules may have different part numbers between years, so verification is recommended. The 2007 G35 sedan was replaced by the G37, but the coupe continued with the same platform through 2007.

The VQ35DE 3.5L V6 in the 2004 G35 is generally a reliable and durable engine when properly maintained. With regular oil changes every 3,000-5,000 miles using quality synthetic oil, these engines commonly exceed 200,000 miles. The timing chain design eliminates timing belt replacement concerns, though the chain tensioners should be inspected around 150,000 miles. Key maintenance items include replacing the camshaft position sensors preventively around 100,000 miles and keeping the intake system clean. The engine’s main weakness is sensitivity to poor maintenance, particularly infrequent oil changes which can cause premature wear to the variable valve timing components.
