Interference suppression resistance (2) is tuned to STIHL machines for the optimal spark and efficiency. This protects the machine’s ignition module from early failure.

The temperature resistance is achieved by differently designed insulators. A cold candle can give off a lot of temperature via the cylinder head, but with a cold candle exactly this is strongly prevented. The heat value has nothing to do with the strength or performance of a spark plug. A cold spark plug in a cold (weak) engine will oil or soot and can therefore break without damaging the engine itself. A hot spark plug in a racing engine burns up and damages the engine ,usually severely.

Spark plugs are a key part of maintaining a petrol power tool, especially STIHL chainsaws, and you may think that one spark plug is much the same as another. A standard NGK spark plug and NGK spark plugs sold by STIHL may have the same part number stamped on them, but the STIHL NGK spark plug has some key differences.

NGK Lawnmower Sparkplug - BPMR7A

The main differences between the STIHL NGK spark plug (right) and the off the shelf NGK plug (left) are:

High quality NGK spark plug which is designed using the latest technology to give optimum performance over the Lawnmowers entire rev. rangeThe heat value is decisive for the thermal fatigue strength of the spark plug and its self-cleaning effect. A distinction is therefore made between so-called cold and hot spark plugs. The material is ultimately almost only interesting for wear, only the extremely thin iridium electrodes (Ø=0.6mm) have a higher ignition voltage, the spread of the flame front in the combustion chamber improves.
