Spark plug Schmitt Iridium 14-260-SIR (BR8HIX)

Schmitt Iridium spark plug.

Based on the former GDR spark plugs from Isolator, Schmitt has an iridium spark plug with a heat value of 260 for the classic GDR vehicle models from Simson,Tomos,Puch and MZ in its range. The 260 heat value corresponds to a heat value of 8, as is known from NGK spark plugs. The 260 Schmitt candle can therefore also be used in all vehicles that require a heat value of 8 from NGK and have a short 14 thread.

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.
