📆 Recommended Spark Plug Replacement Intervals:

✔️ Copper Spark Plugs – Every 30,000 - 50,000 km
✔️ Platinum Spark Plugs – Every 80,000 - 100,000 km
✔️ Iridium Spark Plugs – Every 100,000 - 160,000 km

🔹 Toyota Hilux Petrol Models 2.7L, 4.0L V6 – Usually 80,000 - 100,000 km with iridium plugs.
🔹 Toyota Hilux Diesel Models 2.4L, 2.8L – Diesel engines use glow plugs instead of spark plugs.

📌 Tip: Replace spark plugs earlier if you drive in dusty o r extreme weather conditions.
