The spark plugs in a 2007 Honda Accord should be torqued to 13 ft-lbs (18 N·m). This applies to both the 2.4-liter four-cylinder and the 3.0-liter V6 models used that year, and it’s important to follow the factory specification exactly to protect the cylinder head threads and ensure proper sealing.
Engines Covered
This article covers the two engine options used in the 2007 Accord. Both the 2.4L four-cylinder and the 3.0L V6 share the same spark plug torque target, though plug type and heat range should still match Honda’s OEM recommendations.
2.4L inline-4 (K-series)
For the 2.4L inline-4 engine, tighten each spark plug to 13 ft-lbs (18 N·m). Use the correct heat range and plug type as specified by Honda, and avoid over-tightening which can damage the aluminum cylinder head.
3.0L V6 (J-series)
The 3.0L V6 engine in the 2007 Accord also uses a torque specification of 13 ft-lbs (18 N·m) for each spark plug. As with the four-cylinder engine, ensure you follow Honda’s OEM recommendations for plug type and installation procedure.
Official Torque Specification
The following list summarizes the official torque values by engine for the 2007 Honda Accord. This helps ensure proper seating and long-term reliability of the spark plugs.
- 2.4L I4 (K-series): 13 ft-lbs (18 N·m)
- 3.0L V6 (J-series): 13 ft-lbs (18 N·m)
Concluding note: Always refer to the official service manual or Honda’s published guidelines for model-specific notes. Use a calibrated torque wrench, replace spark plugs with OEM equivalents, and avoid using anti-seize on modern spark plugs as recommended by Honda. After installation, re-check torque after the engine has cooled to ensure nothing loosened during heat cycling.
Summary
In short, the 2007 Honda Accord requires spark plugs to be torqued to 13 ft-lbs (18 N·m) for both the 2.4L four-cylinder and the 3.0L V6 engines. Stick with OEM plug types, proper torque tools, and the guidance in the factory manual to maintain engine integrity and performance.
