The plugs are almost half the cost of Denso and they perform just as well. I would recommend these plugs. Review: Solid, reliable park plugs - I got these for my 2002 GS430 and boy do they help get all the power out of my engine. I have an exhaust leak and trans leak that leads to a laggy bogged down performance, but by swapping out with these plugs yearly I can keep the power more responsive. I tried other plugs, but these seem to do the best for me in my case. Installation was straight forward and these tightened in place great with a little bit of antiseize. ## Features - The information below is per-pack only - Double Iridium firing pin and ground electrode inlay provide 4X longer service life compared to standard copper plugs - 360° continuous laser weld fuses corrosion resistant iridium firing pin to base for increased durability - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Bosch Automotive | | Brand | Bosch Automotive | | Item Weight | 1.6 ounces | | Product Dimensions | 4 x 7 x 9 inches | | Item model number | 9603 | | Manufacturer Part Number | 9603 | ## Product Details - **Brand:** Bosch Automotive - **Core Material:** Iridium - **Top Material Type:** Iridium ## Images ![Bosch Automotive (9603) OE Fine Wire Double Iridium Spark Plug - Single (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/610qEbONlPL._AC_UF1000,1000_QL80_.jpg) ![Bosch Automotive (9603) OE Fine Wire Double Iridium Spark Plug - Single (Pack of 2) - Image 2](https://m.media-amazon.com/images/I/610qEbONlPL._SS80_.jpg) ![Bosch Automotive (9603) OE Fine Wire Double Iridium Spark Plug - Single (Pack of 2) - Image 3](https://m.media-amazon.com/images/I/610qEbONlPL.jpg) ![Bosch Automotive (9603) OE Fine Wire Double Iridium Spark Plug - Single (Pack of 2) - Image 4](https://m.media-amazon.com/images/I/7146NFBC01L._AC_UF1000,1000_QL80_.jpg) ![Bosch Automotive (9603) OE Fine Wire Double Iridium Spark Plug - Single (Pack of 2) - Image 5](https://m.media-amazon.com/images/I/7146NFBC01L._SS80_.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good performance and better gas mileage. *by Q***Q on October 1, 2025* The plugs I received were made in Germany.
