NGK BKR5EIX Iridium IX Spark Plug – Stock No. 6341
The NGK BKR5EIX is a high-quality iridium spark plug designed for reliable ignition and long life. Its fine-wire iridium centre electrode needs less voltage to spark, which helps cold starts, smooth idle, and clean combustion. It also resists wear, so performance stays consistent over a longer service interval.
Use it as a performance-focused replacement where your engine specifies BKR5EIX. It suits many petrol engines that require an M14 x 1.25 gasket-seat plug with 19 mm reach and NGK heat range 5. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Fine-wire 0.6 mm iridium tip for strong, stable spark
- Nickel ground electrode with tapered cut for improved flame kernel
- Resistor type to reduce electrical noise (helps with radio and ECU)
- Built-in gasket seat for proper sealing and heat transfer
