Review: Perfect as Always - Great plug as always with NGK. Used it with my Predator 212 Non Hemi engine for my trail minibike project. Very bright strong spark when I tested it. Never had an issue with any NGK products, best in the game! Review: Great plug for portable generators - Running this plug in my Champion 3500 inverter generator that we power our camper with, and also in the Champion generator that powers my workshop. Over 300 hours on each generator with this plug... both start on the first pull every time. Take that Torch spark plug out, throw it as far away as you can, and replace with NGK... you'll be glad you did. ## Features - Fit type: Vehicle Specific - Designed to operate over a much wider heat range than ordinary plugs - Patented triple gasket sealing process eliminates the possibility of combustion gas leakage - Solid copper core and nickel tipped electrode provide a longer plus life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000UK1Y00 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #70,591 in Automotive ( See Top 100 in Automotive ) #489 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Customer Reviews | 4.8 out of 5 stars 259 Reviews | | Global Trade Identification Number | 00087295166376 | | Included Components | 6637 | | Item Weight | 50 Grams | | Manufacturer | NGK | | Manufacturer Part Number | BPR6EIX | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | 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 | 14mm | | Top Material Type | Ceramic | | UPC | 826732665276 087295166376 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car | ## Product Details - **Brand:** NGK - **Core Material:** Iridium - **Thread Size:** 14mm - **Top Material Type:** Ceramic - **Vehicle Service Type:** Car ## Images ![NGK 6637 Iridium IX Spark Plug - BPR6EIX, 1 Pack - Image 1](https://m.media-amazon.com/images/I/61Qs2owcf+L.jpg) ![NGK 6637 Iridium IX Spark Plug - BPR6EIX, 1 Pack - Image 2](https://m.media-amazon.com/images/I/81k88MpIu7L.jpg) ![NGK 6637 Iridium IX Spark Plug - BPR6EIX, 1 Pack - Image 3](https://m.media-amazon.com/images/I/71cf7nNNuBL.jpg) ![NGK 6637 Iridium IX Spark Plug - BPR6EIX, 1 Pack - 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.
