Spark Plugs: what it does & when to replace it
Spark plugs ignite the air-fuel mixture in each cylinder. Worn plugs cause rough idle, misfires, hard starting, hesitation, and reduced fuel economy. Service intervals vary widely by plug type: copper plugs last around 50,000 km, while iridium and platinum plugs can last 100,000–160,000 km. Always match the manufacturer heat range and gap. Replacement is a moderate DIY job — straightforward on inline engines but harder on V-engines where the rear bank is hard to reach. Electric vehicles do not use spark plugs at all.
DIY difficulty: Moderate DIY (gap matters; harder on V-engines). Always confirm the correct part for your exact build by VIN before buying.

How to replace the spark plugs on a 2022 Lexus NX
- 1With the engine cool, remove the engine cover and disconnect one coil pack or plug lead at a time (do them one at a time to keep firing order).
- 2Blow out debris from the plug well, then unscrew the old plug with a spark plug socket.
- 3Check the new plug’s gap against the manufacturer spec and adjust only if needed.
- 4Thread the new plug in by hand to avoid cross-threading, then torque it to spec.
- 5Reconnect the coil/lead (a dab of dielectric grease helps) and repeat for each cylinder.
⚠ Match the exact plug and heat range for your engine; V-engines’ rear bank can be hard to reach.
These are general steps for the ignition category. Exact fastener locations, torque values, and the correct part number depend on your 2022 Lexus NX’s build — confirm by VIN before you start.
