Spark plug Naraku Iridium 14-R8-SIR (BR8HIX)

Description

The big advantage of an iridium spark plug is the very thin center electrode. The ignition voltage is distributed over a small area, creating a strong and concentrated spark, which leads to clean combustion even under extreme conditions. In addition, coking of the electrode is reduced, which significantly extends its durability.
The durability of iridium spark plugs is many times higher than that of standard spark plugs. Fuel consumption is reduced and the combustion chamber remains free of combustion residues for longer.
