The NGK IZFR6K-11 Iridium spark plug is the iridium fitment for several Honda petrol models including the Accord, CR-V and Civic. It's the NGK-recommended iridium plug for these engines, a direct OEM-spec replacement.
The fine-wire iridium centre electrode fires a tighter, more focused spark than copper, delivering smoother idle, cleaner combustion, and better cold starts. Iridium holds its gap far longer than a standard plug, keeping ignition consistent and stretching out service intervals.
Direct-fit, OEM-spec replacement. No tuning changes — just a sharper, longer-lasting spark.
