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 | 147,832 in Automotive ( See Top 100 in Automotive ) 751 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 163 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 ] | | Number of Items | 1 | | Number of Packs | 1 | | 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 ![NGK Spark Plug LMAR8BI-9 Laser Iridium 91909 - Image 1](https://m.media-amazon.com/images/I/81gzo4iJZRL.jpg) ![NGK Spark Plug LMAR8BI-9 Laser Iridium 91909 - Image 2](https://m.media-amazon.com/images/I/61eEqPTencL.jpg) ![NGK 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!
