Yes, replacing OEM plugs with aftermarket iridium o r platinum spark plugs is widely recommended. Based on Pakistani user experiences:

NGK Iridium IX BKR6EIX – Excellent longevity, smoother idle

Denso Iridium TT – Slightly more expensive, good for fuel economy

Bosch Platinum+4 – Decent option, but not as popular

NGK Iridium is the most recommended for Alsvin due to local availability and long-lasting performance 30,000–40,000 km lifespan.
