NGK LFR6AIX-11 Iridium IX Spark Plug for Toyota Innova (Petrol)

The NGK LFR6AIX-11 Iridium IX spark plug is the iridium fitment for the Toyota Innova — India's workhorse MPV. It's the NGK-recommended iridium plug for the petrol Innova, a direct OEM-spec replacement.

The 0.6mm 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 — ideal for a vehicle that clocks serious miles.

Direct-fit, OEM-spec replacement. No tuning changes — just a sharper, longer-lasting spark.

Fitment (NGK-confirmed)
