spark plug Naraku iridium 14-R8-SIR (BR8HIX) NK14-R8-SIR
Naraku iridium spark plug.
Great advantage of an iridium spark plug is the very thin centre electrode. The ignition voltage is distributed over a small area only and thus produces a strong and concentrated spark, which leads to a clean combustion even under extreme conditions. In addition, coking of the electrode is reduced, which significantly increases its durability.
The durability of iridium spark plugs is many times higher compared to standard spark plugs. Fuel consumption is reduced and the combustion chamber remains free of combustion residues for longer.
