NGK BKR6EP-13 Spark Plug (Stock No. 2550) – Laser Platinum, 1.3 mm Gap
This NGK BKR6EP-13 is a platinum spark plug designed for long life and stable performance. It uses a resistor to reduce electrical noise and a projected tip to improve cold starts and throttle response. The 1.3 mm preset gap suits many standard petrol engines. It is a direct replacement where this part number is specified.

Why it matters: a clean, strong spark helps the engine burn fuel efficiently. This can improve starting, idle quality, and throttle response. The platinum centre electrode resists wear, so performance stays consistent for longer service intervals than a standard copper plug.
- Stable spark and smoother running under load.
- Longer life than standard nickel plugs due to platinum centre.
- Resistor design reduces radio interference and ECU noise.
Fitment guidance
Suitable for petrol engines that specify a 14 mm, 19 mm reach, gasket-seat, resistor plug with a 1.3 mm gap and NGK heat range 6. This includes many mainstream 4-cylinder engines from the same era. Use the vehicle lookup to confirm, or check the Vehicle Fitment tab for full details.
Install notes: Always confirm gap and torque to the vehicle manufacturer’s spec. If adjustment is needed, handle the fine electrodes carefully to avoid damage.
