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.
