The 2005 Acura RL comes equipped with Honda’s J35A8 3.5-liter V6 engine producing 300 horsepower and 275 lb-ft of torque. This VTEC engine features aluminum construction, dual overhead cams, and variable valve timing. It’s paired exclusively with a 5-speed automatic transmission and Acura’s Super Handling All-Wheel Drive (SH-AWD) system. The engine uses a drive-by-wire throttle system and includes Variable Cylinder Management technology that can deactivate three cylinders under light load conditions to improve fuel economy. This powerplant provides strong acceleration while maintaining reasonable fuel efficiency for a luxury sedan of this size and capability.

The 2005 Acura RL shares most parts with the 2005-2008 model years of the same generation. Engine components from the J35A8 are largely interchangeable across these years, though some sensors and emissions components may vary. Body panels, interior trim, and suspension components are generally compatible within the 2005-2008 range. However, the 2009-2012 second generation RL has different body panels, interior components, and some mechanical differences. Transmission parts are compatible within 2005-2008, but electrical components may have different part numbers due to software updates. Always verify specific part numbers when sourcing components, as running changes occurred during production that can affect compatibility even within the same model year.

The J35A8 3.5L V6 in the 2005 Acura RL is generally reliable when properly maintained, but has some notable issues. The Variable Cylinder Management system can cause oil consumption and carbon buildup problems if not addressed with regular maintenance. The engine itself is robust and can easily exceed 200,000 miles with proper care, including regular oil changes every 5,000 miles using the correct viscosity. The timing belt should be replaced every 105,000 miles along with the water pump. Avoid extended oil change intervals and use quality synthetic oil to prevent VCM-related issues. The engine’s aluminum construction makes it sensitive to overheating, so maintain the cooling system properly and address any leaks immediately.
