The spark plugs on the 2016 Honda Civic are torqued to 13 N·m (about 9.5 ft-lb) for the most common 1.5-liter turbocharged engine used in US-market Civics that year. If your car uses the 2.0-liter engine, the torque specification differs and you should consult the factory service manual or a Honda dealer for the exact value.
Engine options and official torque specs
Because the 2016 Civic offered two four-cylinder powertrains, the torque setting for spark plugs varies by engine. The following reflects the primary variants used in that model year.
- 1.5-liter turbocharged engine (L15B7): Spark plugs torque to 13 N·m (9.5 ft-lb).
- 2.0-liter naturally aspirated engine (K-series): Torque specification varies by plug type and market; consult the factory service manual for the exact value (typically higher than the 1.5L turbo).
When replacing spark plugs, always verify the exact torque for your specific engine variant in the service manual or with a Honda dealership. Use the recommended plug type and gap, and avoid over-tightening to prevent thread or cylinder head damage.
Takeaways
For the 2016 Civic’s most common configuration, expect 13 N·m (9.5 ft-lb) of torque for each spark plug. If your model uses the 2.0-liter engine, check the official service data to confirm the correct torque, as it can differ by market and plug type. Always follow the exact factory guidance to ensure proper sealing and longevity of the threads.
What is the spark plug gap for a 2016 Honda Civic?
0.032"
They are pre-gapped at 0.032" (factory spec). Note: we recommend double-checking for safety and adjusting gaps based on your modifications. Reduced gapping to 0.020" is recommended for high boost and high power engines.

What is the torque on spark plugs for a 2016 Honda Civic?
Torque the spark plug to 22 N.m (2.2 kg-m, 16 Ib-ft). (If you do not have a torque wrench, tighten the spark plug 2/3 turn after it con- tacts the cylinder head.) Tighten the spark plugs carefully. A spark plug that is too loose can overheat and damage the engine.
