NGK LKAR9BI-9 Iridium Spark Plug – 6205
The NGK LKAR9BI-9 is a high-quality iridium spark plug designed for reliable ignition under high heat and load. It delivers a strong, consistent spark, helping the engine start easily, idle smoothly, and maintain clean combustion. The iridium tip resists wear, so performance stays stable for longer service intervals compared to standard copper plugs.
- Fine iridium centre electrode for a strong, focused spark and cleaner combustion.
- Platinum pad on the ground electrode for long life and consistent gap.
- Resistor design to reduce electrical noise that can affect the ECU.
Always confirm fitment using the vehicle lookup or the Vehicle Fitment tab before ordering.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
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.
