Questions & Answers
Is this a genuine NGK part?
Yes, these are 100% genuine NGK Laser Iridium spark plugs. We do not sell counterfeit parts; authenticity is guaranteed for all components purchased at 4boats.co.uk.
Are these plugs pre-gapped?
Yes, the IZFR6K11 comes pre-gapped at 1.1mm (0.044"). However, we always recommend verifying the gap against your engine's specific service manual before installation, as transit or handling can occasionally shift the setting.
What are the benefits of Laser Iridium over standard plugs?
Laser Iridium plugs provide a much higher melting point and superior electrical conductivity compared to standard nickel plugs. This results in faster cold starts, more stable idling, and reduced voltage requirements, which prolongs the life of your ignition coils.
Note: Always verify your original part number against the cross-references provided. For precise fitment, check your outboard's serial number or consult your owner's manual.
