Designed for durability with a narrow center electrode, it ensures longer service life and smoother engine operation, making it a top choice for both motorsport enthusiasts and everyday drivers seeking reliable, high-performance ignition. ## Description With the high-performance Iridium IX spark plug, NGK now makes advanced "Iridium" technology available for older motorcycles and vehicles! Because it is a precious metal, Iridium makes it possible to make the centre electrode of the spark plug significantly narrower. This has the advantage that the mixture can flow better between the centre electrode and the earth electrode, resulting in better ignition. Compared to standard spark plugs, the chance of a misfire is greatly reduced and fuel is optimally utilised. At the same time, iridium wears far more slowly, providing a longer service life than standard plugs despite the small diameter. Further advantages: Excellent acceleration values, optimised ignition behaviour, better and smoother engine operation and a longer service life - while at the same time providing lower fuel consumption. An investment that pays off! In motor sports as well as in daily use, iridium is a high-tech metal that provides absolute top performance. That's why more and more manufacturers are installing iridium spark plugs in their standard production models. When will you switch? 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: Para Continental GT 535 - Una buena bujia a un buen precio. Noto el arranque más enérgico incluso a patada. ## Features - Quality/Durability - Durability - robustness - The best products ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000UK1Y00 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #127,662 in Automotive ( See Top 100 in Automotive ) #878 in Automotive Performance Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Copper | | Core material | Copper | | Customer Reviews | 4.7 out of 5 stars 259 Reviews | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 00087295166376 | | Item Type Name | Spark plug | | Item Weight | 50 Grams | | Manufacturer | NGK SPARK PLUGS UK LTD | | Manufacturer Part Number | BPR6EIX | | Model Number | 6637 | | Number of Items | 1 | | 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 Count | | Vehicle service type | Car | ## Product Details - **Brand:** NGK - **Core material:** Copper - **Thread size:** M12, M14, M18 - **Top material type:** Metal - **Vehicle service type:** Car ## Images ![Spark Plug BPR6EIX Iridium IX 6637 - Image 1](https://m.media-amazon.com/images/I/61Qs2owcf+L.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.

I used the BPR6EIX for my champion 6500w geni and the results were apparent with the first start. I will probly switch all of the plugs in my power equipment for ease of starting. ## Frequently Bought Together - NGK 6637 Iridium IX Spark Plug - BPR6EIX, 1 Pack - BPR6ES NGK Spark Plug for Honda Engines & Other Small Engines (One Spark Plug) - CTA Tools 3235 Spark Plug Gapper --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/427615640-spark-plug-bpr6eix-iridium-ix-6637](https://www.desertcart.co.uk/products/427615640-spark-plug-bpr6eix-iridium-ix-6637) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-30*
