NGK BKR5EQUPA Spark Plug – Quad Ground, Laser Platinum
This NGK spark plug is built for consistent ignition and long service life. It uses a fine platinum centre electrode for a strong spark with less voltage. Four ground electrodes help maintain reliable firing as the plug wears.
The projected tip places the spark where the mixture burns best. A built-in resistor reduces electrical noise that can affect the radio or ECU. It is pre-gapped for typical factory settings and is suited to petrol engines that specify a 14 mm thread with long reach.
Use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
- Stable spark under load for smoother running
- Long service interval thanks to platinum centre and multi-ground design
