NGK CR6HIX Iridium IX Spark Plug for Hero Splendor / Passion / HF Deluxe & Honda Activa, Dio (100-110cc Commuter)

The NGK CR6HIX Iridium IX spark plug is the iridium upgrade for India's most-ridden commuter engines — the 100-110cc workhorses from Hero, Honda, Bajaj, TVS, Yamaha and more. It's the NGK-recommended iridium fitment for these machines, so it drops straight in where your standard CR6-series plug sits.

The 0.6mm fine-wire iridium centre electrode lights a tighter, more focused spark than a copper plug. On a daily commuter that means easier starts, a steadier idle, and cleaner running — and because iridium holds its gap far longer, you stretch the miles between plug changes. For a bike that earns its keep every single day, that's real value.

Direct-fit, OEM-spec, no tuning changes. Just a sharper, longer-lasting spark.
