The Nickel-plated rolled threads provide maximum resistance to corrosion - ensuring the spark plug removes easily from the cylinder head without galling - and do not require anti-seize during installation - saving time.

Unlock the performance in your engine with Bosch Double Iridium Spark Plugs. Review: The REAL GERMAN Deal. - I waited to see if these were MADE IN GERMANY, and they were! A box of 10 is the only way to buy plugs, so you get matched production batch codes. My part ordered is one step cooler (for those who know what that means) than what my BMW X5M is supposed to have, which is exactly what I needed for how it has been re-tuned. Unfortunately, some Bosch plugs are made in China, which I will have nothing to do with for my car. Glad I won't be sending these back. Review: Gran compra - Muy buenas bujías hasta ahorita sin ningún problema. Muy feliz con la compra. ## Features - 360-degree laser welded ultra-fine wire iridium firing pin provides better ignitability - reducing voltage requirements up to 24% - and enhanced durability - Meets or exceeds manufacturer design requirements for OE fit, form, and function for modern gasoline engines - including Gasoline Direct Injection (GDI) engines ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0027ZKDG2 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #86,634 in Automotive ( See Top 100 in Automotive ) #552 in Automotive Replacement Spark Plugs | | Brand | Bosch | | Brand Name | Bosch | | Compatible with Vehicle Type | Car, SUV, Truck | | Core Material | Iridium | | Customer Reviews | 4.5 out of 5 stars 171 Reviews | | Gap Size | 1.1 millimeters | | Global Trade Identification Number | 00028851034449 | | Included Components | Spark Plugs | | Item Type Name | Spark Plugs | | Item Weight | 3.36 ounces | | Manufacturer | Bosch Automotive | | Manufacturer Part Number | 9673 | | Manufacturer Warranty Description | Limited | | Model Number | 9673 | | OEM Equivalent Part Number | Consultar con el fabricante | | Thread Size | 14 | | Top Material Type | iridium | | UPC | 028851034449 | | Unit Count | 4 Count | | Vehicle Service Type | Car, SUV, Truck | ## Product Details - **Brand:** Bosch - **Core Material:** Iridium - **Thread Size:** 14 - **Top Material Type:** iridium - **Vehicle Service Type:** Car, SUV, Truck ## Images ![BOSCH 9673 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 1](https://m.media-amazon.com/images/I/71FZXJroy2L.jpg) ![BOSCH 9673 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 2](https://m.media-amazon.com/images/I/61GmL0w8STL.jpg) ![BOSCH 9673 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 3](https://m.media-amazon.com/images/I/61SR5jxEiPL.jpg) ![BOSCH 9673 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 4](https://m.media-amazon.com/images/I/51Q9udIwTTL.jpg) ![BOSCH 9673 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 5](https://m.media-amazon.com/images/I/61xQszqJFIL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The REAL GERMAN Deal. *by J***A on June 16, 2026* I waited to see if these were MADE IN GERMANY, and they were!
