NGK Laser Iridium spark plugs are first-class technology of the highest calibre! The precious metal means that the centre electrode of the spark plug can be kept much narrower, allowing the petrol-air mixture to flow more easily between the centre and ground electrodes and therefore be better ignited. The result: Significantly improved cold start behaviour and more efficient combustion than with conventional spark plugs, the fuel is optimally utilised. The advantages: Improved ignition behaviour, optimised starting behaviour and smoother running – with lower fuel consumption and reduced environmental impact. An investment that pays off! In both motorsport and everyday use, the high-performance metal iridium ensures top performance. Laser Iridium spark plugs provide the ideal ignition for modern engines. The most important car manufacturers rely on this technology, which is also available to the aftermarket. Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. Note: Please observe the general installation instructions before installation! Review: High quality long lasting plug! - Why did you choose this product over others?: I wanted a 'long lasting high performance plug for my Thruxton R and this appeared to fit the bill! I changed several things at once (stale fuel, redex, plugs, air filter so it's not possible to say I 'noticed a marked improvement' just because of this! Review: Super Plugs.👍👍 - I got fed up keep changing plugs on a Yamaha MT07 Tracer. Every time you have to change the plugs you have to half strip the bike. 😖😖😖. So now I have these plugs fitted which should last at least THREE +times longer. 👍👍👍. ## Features - Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. - Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. - Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. - Note: Please observe the general installation instructions before installation! - Scope of delivery: 1x NGK spark plug LMAR8BI-9 Laser Iridium ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06X9CKC1N | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | 175,486 in Automotive ( See Top 100 in Automotive ) 868 in Car Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Motorcycle | | Core Material | Iridium | | Core material | Iridium | | Customer Reviews | 4.6 out of 5 stars 157 Reviews | | EU Spare Part Availability Duration | 10 Years | | Gap Size | 16 Millimeters | | Global Trade Identification Number | 00087295919095 | | Included Components | nothing | | Item Type Name | NGK LMAR8BI-9 IRIDIUM Spark Plug | | Item Weight | 0.02 Kilograms | | Manufacturer | NGK | | Manufacturer Part Number | LMAR8BI-9 | | Manufacturer Warranty Description | producer | | Model Number | LMAR8BI-9 [ 91909 ] | | OEM Equivalent Part Number | LMAR8BI-9 | | Thread Size | RM | | Thread size | RM | | Top Material Type | Iridium | | Top material type | Iridium | | UPC | 779420925391 087295919095 | | Unit Count | 1.0 count | | Vehicle service type | Motorcycle | ## Product Details - **Brand:** NGK - **Core material:** Iridium - **Thread size:** RM - **Top material type:** Iridium - **Vehicle service type:** Motorcycle ## Images ![Spark Plug LMAR8BI-9 Laser Iridium 91909 - Image 1](https://m.media-amazon.com/images/I/81gzo4iJZRL.jpg) ![Spark Plug LMAR8BI-9 Laser Iridium 91909 - Image 2](https://m.media-amazon.com/images/I/61eEqPTencL.jpg) ![Spark Plug LMAR8BI-9 Laser Iridium 91909 - Image 3](https://m.media-amazon.com/images/I/71nkpzwtrCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality long lasting plug! *by A***R on 22 June 2025* Why did you choose this product over others?: I wanted a 'long lasting high performance plug for my Thruxton R and this appeared to fit the bill!
