Today, the Automotive Components business has expanded to become the world’s top global manufacturer of OE and Aftermarket ignition and vehicle electronics parts. Benefit from our decades of know-how and outstanding expertise in Original Equipment and spare parts business. We promise: Under our new company name Niterra (formerly NGK SPARK PLUG), we continue to be the reliable partner at your side today and tomorrow. Ultimate Engine Combustion NGK spark plugs deliver smooth engine starting and running, general engine performance and efficiency as well as the reduction of harmful emissions. Niterra is the world's leading manufacturer of spark plugs for original equipment and the aftermarket. Car and motorbike manufacturers, dealers and workshops have been relying on the ignition specialist's expertise for decades. With NGK high-performance spark plugs, the Iridium top technology is also available for older vehicle and motorbike models! Using the precious metal iridium, the centre electrode of the spark plug can be kept much narrower, allowing the petrol-air mixture to flow more easily between the centre electrode and the earth electrode and to be ignited more easily. The result: fewer misfires than with conventional spark plugs, the fuel is optimally utilised. An investment that pays off! The advantages: Improved ignition behaviour, optimised cold start behaviour and smoother running – with lower fuel consumption at the same time. In motorsport as in everyday use, the high-performance metal iridium ensures absolute top performance. This is why more and more manufacturers are installing Iridium spark plugs in series production. Excellent starting behaviour: The laser-welded iridium centre electrode (Ø 0.6 mm) minimises the ignition voltage requirement for optimum ignition. Special technology against sooting: Spark plugs with an extremely thin, laser-welded centre electrode and a special technology against ignition problems caused by sooting. Note: Please observe the general installation instructions before installation! Review: bad Prime delivery - This item is very good. However, it was not left by my front door - it was left out side my garden gate which is not locked, so entrance to the front door is child's play. Review: Good plug - Excellent plug. Smoother running and easy starting. ## Features - Optimal ignition performance: The laser-welded iridium centre electrode has a diameter of only 0.6 mm. This keeps the ignition voltage requirement low and ensures a powerful ignition spark. - Long life: Thanks to the precious metal, the Iridium IX spark plug lasts up to twice as long as a standard nickel spark plug and, due to this durability, saves money and installation and removal time. - Full performance over the entire service life: With standard spark plugs, the distance between the electrodes increases over time due to burn-off. The quality of the ignition is impaired and misfiring occurs. With Iridium spark plugs, the electrode gap remains almost constant over the entire service life. - Notes: please read the general installation instructions before installing! - Delivery includes: 1x NGK spark plug BKR6EIX Iridium IX ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000UK1Y00 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 124,636 in Automotive ( See Top 100 in Automotive ) 691 in Car Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Core material | Iridium | | Customer Reviews | 4.6 out of 5 stars 252 Reviews | | EU Spare Part Availability Duration | 5 Years | | Gap Size | 20.8 Millimeters | | Global Trade Identification Number | 00087295166376 | | Included Components | nothing | | Item Type Name | NGK Spark Plug BPR6EIX Iridium IX 6637 | | Item Weight | 50 Grams | | Manufacturer | NGK SPARK PLUGS UK LTD | | Manufacturer Part Number | BPR6EIX | | Manufacturer Warranty Description | producer | | Model Number | 6637 | | OEM Equivalent Part Number | Honda 98079-56844, Mazda 0370 18 110, Peugeot 5962.22, Subaru 49001 0013, Yamaha 94701 00284 | | Thread Size | M12, M14, M18 | | Thread size | M12, M14, M18 | | Top Material Type | Metal | | Top material type | Metal | | UPC | 826732665276 087295166376 | | Unit Count | 1.0 count | | Vehicle service type | Car | ## Product Details - **Brand:** NGK - **Core material:** Iridium - **Thread size:** M12, M14, M18 - **Top material type:** Metal - **Vehicle service type:** Car ## Images ![NGK Spark Plug BPR6EIX Iridium IX 6637 - Image 1](https://m.media-amazon.com/images/I/61Qs2owcf+L.jpg) ![NGK Spark Plug BPR6EIX Iridium IX 6637 - Image 2](https://m.media-amazon.com/images/I/81k88MpIu7L.jpg) ![NGK Spark Plug BPR6EIX Iridium IX 6637 - Image 3](https://m.media-amazon.com/images/I/71cf7nNNuBL.jpg) ![NGK Spark Plug BPR6EIX Iridium IX 6637 - Image 4](https://m.media-amazon.com/images/I/61QsRXGA+gL.jpg) ## Questions & Answers **Q: Is it price for 1 Spark Plug or 4 ?** A: 1 spark plug **Q: How long "should" these last?** A: Well, in a Car no less than 100,000 miles.
