NGK BKR6EIX Iridium IX Spark Plug – Stock No. 6418
The NGK BKR6EIX is a fine-wire iridium spark plug designed for clean ignition, stable idle, and long service life. The 0.6 mm iridium centre tip needs less voltage to fire. This helps cold starts and improves combustion under load. The tapered ground electrode exposes the flame better for a more reliable burn.
Expect smoother running and consistent performance over many miles compared to standard copper plugs. It will not add big power on its own, but it supports tuned engines by maintaining a strong spark at high rpm. It is a resistor plug, so it also helps cut electrical noise that can affect the ECU and audio systems.
Why choose this plug
- Strong, stable spark from a fine-wire iridium tip
- Smoother idle and cleaner cold starts
- Better knock resistance under high load due to reliable ignition
- Longer service life than standard nickel plugs

Fitment notes
This size and reach are widely used across many Japanese and European petrol engines that take an M14 gasket-seat plug with 19 mm reach and a medium heat range. Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
Important: Always match the heat range and gap to your engine and tune. Check the gap before install. If adjustment is needed, only bend the ground strap slightly. Do not touch the fine iridium tip. Install on a cold engine. Tighten to the correct specification for M14 gasket-seat plugs, following manufacturer guidance.
The price displayed is for a single plug, please add the desired amount to your basket.

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.
