Well worth the the price spending for replacement auto parts. Review: they work fantastic for my 2011 mazda 3 2.0l. no gapping needed if stock. - Perfect fit for my 2011, (other years will fit as well, just check.) mazda 3 2.0l. at 189 k it runs like new! (I am not sure how old the other spark plugs were, I bought it used, but they were mazda oem plugs.) took me 15 mins to swap, anybody else has issues then you must of messed up with the type of spark plugs needed or the gaping. (of course each vehicle is different.) driving, idle or accelerating has been top notch, so i assume whatever the gap is set at, my Mazda 3 has not complained and not one single misfires or check engine light. It's been over a week, daily driver. even thru rain. FL driver. as usual, with some statements, people don't know what t f they are talking about. as if they magically believe the opinions based on personal ignorance is the only way to go. point is, who gives a crap where it was manufactured as long as the darn spark plugs perform the way they were designed. that is all. almost 3 months in and they are still performing well. (fl chilly weather or when it's hot, humid and 90's) 6/3/2021 April 2023 and zero issues w these plugs. April 2026. Perfect. :) ## Features - Double Iridium firing pin and ground electrode inlay provide 4X longer service life compared to standard copper plugs - 0.6mm fine wire firing pin provides superior ignitability and performance - 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 | |---------------|-------| | ASIN | B008E7QKBE | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #1,305,967 in Automotive ( See Top 100 in Automotive ) #6,747 in Automotive Replacement Spark Plugs | | Brand Name | Bosch | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.6 4.6 out of 5 stars (366) | | Gap Size | 1.1 Millimeters | | Global Trade Identification Number | 00028851034197 | | Included Components | spark plug | | Item Type Name | Spark Plug | | Item Weight | 1.76 ounces | | Manufacturer | Bosch Automotive | | Manufacturer Part Number | 9617 | | Manufacturer Warranty Description | Limited | | Model Number | 9617_1 | | OEM Equivalent Part Number | 9617 | | Thread Size | M14 | | Top Material Type | Nickel | | UPC | 028851034197 | | Unit Count | 1 Count | ## Product Details - **Brand:** Bosch - **Core Material:** Iridium - **Thread Size:** M14 - **Top Material Type:** Nickel - **Vehicle Service Type:** Car, Truck ## Images ![9617 OE Fine Wire Double Iridium Spark Plug - Single - Image 1](https://m.media-amazon.com/images/I/71FZXJroy2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bosch products are the next best replacement auto engine parts near OEM. *by R***O on January 11, 2025* A great made spark plug.
