Car Spark Plug Replacement Cost in UAE (2026)
Spark plugs are one of the most cost-effective maintenance items on a petrol engine vehicle. A worn spark plug causes misfires, increased fuel consumption, rough idle, and difficulty starting — all of which become noticeably worse in UAE summer heat when the ignition system is under increased thermal stress. Modern iridium and platinum spark plugs last 60,000-100,000 km, but standard copper plugs require replacement every 20,000-30,000 km. UAE drivers often delay spark plug replacement longer than recommended, which leads to catalytic converter damage from unburnt fuel and increased fuel costs over time.

Spark Plug Service in UAE Garages
UAE garage technicians inspect spark plugs for the following conditions: electrode wear (normal end-of-life), carbon fouling (rich mixture or oil burning), oil fouling (piston ring or valve seal wear), blistering (overheating from lean mixture or cooling issues), and cracking (thermal shock from overheating). The plug condition tells the technician about the broader engine health. In UAE, many vehicles run on fuel grades lower than the engine specification (mixing 91 RON and 95 RON is common), which can cause pre-ignition and accelerated plug wear.
