NGK ILFR6J 11K 4458 Spark Plug Iridium ILFR6J11K

The NGK ILFR6J-11K is part of the NGK Laser Iridium range.NGK Laser Iridium is original-equipment specification: the plug type fitted on the production line by many manufacturers. It pairs a laser-welded iridium centre electrode with a platinum pad on the ground electrode so both wearing surfaces are precious metal, which is what allows the very long service intervals modern engines are scheduled for. Consistent ignition over the life of the plug keeps fuel consumption and emissions where the maker intended. Use it as the like-for-like replacement where the vehicle handbook specifies this part number. Cross reference (approximate equivalents): Denso VKH20, SK20HPRL11, 5618; Honda 12290RMX003, 12290RMX013. Equivalents from NGK’s 2024 cross-reference chart – check thread size, reach and seat type before fitting.

Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. Note: Please observe the general installation instructions before installation! Scope of delivery: 1x NGK spark plug ILFR6J-11K Laser Iridium
