Replace Your Civic's Spark Plugs for $18 — Here's Exactly How
The dealer quotes $180 for a 25-minute job. This free checklist covers the 2022 Honda Civic 1.5T — the correct NGK ILFR6H-11 iridium plugs (pre-gapped from the factory), COP removal order, and the exact torque spec that prevents cracked ceramic insulators.
This checklist is a practical starting point. The DIY Mechanic System gives you a clearer path to diagnose the problem, plan the job, and complete the repair.
What this checklist covers
- NGK ILFR6H-11 iridium plugs come pre-gapped at 0.044" for the 1.5T — why re-gapping iridium plugs chips the fine-wire tip and causes misfires at high RPM
- COP coil-on-plug removal sequence and the hidden 10mm bolt under the engine cover most DIYers miss on the first attempt
- 13 ft-lbs torque spec and why the Civic's aluminum head strips instantly if you overtighten — plus the thread-chaser trick if it does
