How much torque do you apply on the spark plug for your 2008 civic si?

Answer 1

For a 2008 Honda Civic Si, the recommended torque specification for the spark plugs is typically around 13 lb-ft (pound-feet) or 18 Nm (Newton-meters). It's important to use a torque wrench to ensure proper tightness without over-tightening, which can damage the cylinder head. Always refer to the vehicle’s service manual for the most accurate specifications and guidance.
