The MDX, with its family-oriented design, benefited from the J37’s performance, giving it an edge in the luxury SUV market with added power.

Acura RL and Honda Legend
Both esteemed for luxury and smooth ride, the J37 uplifted their status with enhanced V6 power, bolstering their reputation for refinement and strength.

Historical Evolution and Updates

Over time, we’ve seen the J37 engine evolve to adapt to the demands of performance and efficiency. Notably, it commenced its journey in Acura models around 2007 and has since then undergone various enhancements and modifications.

For instance, earlier versions like the J35A4 and J32A2 established the groundwork for what would become the more advanced J35A3 and eventually the J37 family engine. Each leap marked an improvement in Acura’s pursuit of creating engines that deliver a powerful and responsive ride.

Whether it was through incremental increases in displacement or tuning for better output, the J37’s historical evolution is a testament to Acura’s dedication to automotive excellence.

Reliability and Maintenance

In our experience with the Honda J-series, specifically the J37 engine, we’ve noticed it stands out for its durability and reliability.

The engine’s longevity heavily relies on regular maintenance. Proper servicing is crucial to achieving its full lifespan potential.

Common Issues:

  • Valve adjustments necessary at certain intervals can be a mild inconvenience.
  • Regular timing belt replacements after approximately every 60,000 to 100,000 miles to prevent failure.

We find that the engine’s construction is fairly traditional, so repairs don’t usually come with excessive costs, providing a cost-effective ownership experience.

Regular oil changes and filter replacements are key to preventing the problem of excessive oil consumption. This issue can start to appear around 150,000 miles.
