Best price anywhere Review: I replaced plugs that had over 80, 000 miles ... - I replaced plugs that had over 80,000 miles on it mainly to get rid of "Restricted Performance" messages, hesitations at various speeds, and low end sluggishness. What I found was that the plugs were not the problem. It did improve performance, but, unfortunately, there are other issues unrelated. I could not give it a five star review because of this. I do expect that, once these issues are resolved, I will notice an improvement in my Jaguar's performance. ## Features - 4 pack NGK Laser Iridium 7866 Spark Plug - Genuine NGK Parts - Includes original packaging and hardware - Direct replacement auto parts - Confirm vehicle fitment with desertcart Confirmed Fit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BS3ZWF6 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #3,796,231 in Automotive ( See Top 100 in Automotive ) #16,348 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car, Truck | | Core Material | Platinum | | Customer Reviews | 4.7 out of 5 stars 10 Reviews | | Global Trade Identification Number | 00087295078662 | | Included Components | 7866 | | Item Highlight | Replaces 4550157 AJ84575 C2A1535 LR005253 4503 4701 IK16TT PK16TT V99-75-0063. 80k-100k mileage rated. | | Manufacturer | NGK | | Manufacturer Part Number | IFR5N-10 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | IFR5N-10 | | Number of Items | 1 | | OEM Equivalent Part Number | IFR5N-10 | | Thread Size | 14mm | | Top Material Type | Metal | | UPC | 087295078662 | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** NGK - **Core Material:** Platinum - **Thread Size:** 14mm - **Top Material Type:** Metal - **Vehicle Service Type:** Car, Truck ## Images ![NGK Laser Iridium 7866 IFR5N-10 Laser Iridium Spark Plug, 4 Pack - Image 1](https://m.media-amazon.com/images/I/61bG0S3eHnL.jpg) ![NGK Laser Iridium 7866 IFR5N-10 Laser Iridium Spark Plug, 4 Pack - Image 2](https://m.media-amazon.com/images/I/61EvrbEEptL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super long life plug *by S***M on June 22, 2019* These are the OEM plugs for my 2009 Jaguar XK.
