NGK Iridium IX Spark Plug – BPR8HIX (Stock 6742)
The NGK BPR8HIX is an Iridium IX spark plug designed for reliable ignition under high heat and load. Its fine-wire iridium centre electrode needs less voltage to spark, which helps starting, keeps idle smooth, and resists fouling. It also holds its sharp edge longer than copper plugs, so performance stays consistent for more miles.
Use this plug where the engine calls for an NGK heat range 8, projected-tip, resistor type plug with 14 mm threads and 12.7 mm reach. This is common on many performance motorcycles, two-strokes, and powersports engines.
Always match the heat range and dimensions to your manufacturer’s specification to avoid misfires or engine damage.
- Fine-wire iridium tip for strong, stable spark and long life
- Projected, resistor design for clean running and reduced radio noise
- Cold heat range (8) suited to higher temperatures and hard use

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
