Says these were supposed to be gapped at .050 but the whole set was gapped at .055 to .063 it's good that I always check the gap before installing or I'd be having a few issues ## Features - Often designated as the original equipment NGK Spark Plugs are the best combination of performance and longevity - Offering the quality, reliability, and durability you expect from OEM manufacturers - NGK is the world's largest OEM spark plug supplier - Please check your application before purchasing to ensure this OEM part fits your vehicle including the engine, drivetrain and the quantity you need - This listing is for 8 spark plugs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0033I4W6E | | Brand Name | NGK | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Customer Reviews | 4.8 4.8 out of 5 stars (649) | | Included Components | 7164 | | Item Weight | 0.72 Pounds | | Manufacturer | NGK | | Manufacturer Part Number | 7164 TR55IX | | Model Number | 7164 | | OEM Equivalent Part Number | FORD%1315691 | | Thread Size | 14mm | | Top Material Type | Iridium | | UPC | 087295071649 | | Unit Count | 8.00 本 | ## Product Details - **Brand:** NGK - **Core Material:** Iridium - **Thread Size:** 14mm - **Top Material Type:** Iridium - **Vehicle Service Type:** Car ## Images ![NGK Iridium IX Spark Plug TR55IX # 7164 - Image 1](https://m.media-amazon.com/images/I/71L9INo8EwL.jpg) ![NGK Iridium IX Spark Plug TR55IX # 7164 - Image 2](https://m.media-amazon.com/images/I/71JpM+J1PJL.jpg) ![NGK Iridium IX Spark Plug TR55IX # 7164 - Image 3](https://m.media-amazon.com/images/I/61Gr0+1sEvL.jpg) ![NGK Iridium IX Spark Plug TR55IX # 7164 - Image 4](https://m.media-amazon.com/images/I/61RgVzsIccL.jpg) ![NGK Iridium IX Spark Plug TR55IX # 7164 - Image 5](https://m.media-amazon.com/images/I/514VccQuLEL.jpg) ## Questions & Answers **Q: Would these work good in a supercharged 04 mustang ?** A: No. You need a smaller gap like .032 - .035 depending how much boost you got. These are gapped at .059 which would take too much bending to gap it down. NGK says not to change gap more than .008. NGK TR6ix would work better with preset gap at .039 **Q: The NGK TR55IX plugs do not fit a 2002 Tahoe, 5.3l flexfuel. Must use the TR5IX. Too many places including parts stores are selling the wrong plug.** A: I don’t know why you think the TR55IX won’t work, just a slightly cooler plug than the TR5IX. In a lot of climates, it would probably help more than hurt. **Q: What is the gap preset on this plug?** A: Hi, Set of 8 TR55IX NGK Iridium IX plugs Gap: 1.5mm Heat: "5" Seat: taper NOTE: these are very similar to TR5IX, the difference is: TR5IX have 1.0mm gap and TR55IX have 1.5mm gap. They are the same heat rating, length, etc. NOT SUITABLE FOR Ford TS50 with alloy heads. Hope this info will help you make a decision. **Q: Are these "one piece" spark plugs unlike the three piece design that comes as oem 2005 f150 4.6l?** A: I installed these plugs in a 2002 Mercury Mountaineer 4.6 liter and they were one piece....easy to install ...make sure you use anti seize compound on the threads...and gap them properly to specs...the motorcraft plugs are prone for breaking off inside the vehicles because they get too hot and become brittle after awhile...and most people dont change them every 40-50,000 miles...definetely recommend the NGK's ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***E on September 22, 2023* Preis Leistung in Ordnung ### ⭐⭐⭐⭐⭐ Review *by M***E on September 26, 2023* Looked around and tried to order locally but no parts stores have them available for a 1995 lt1, I've used this plug in my truck for the last 4 tune ups and they last aswell has saves a few bucks on fuel.
