I use these on a ZX14, ZX9R, and on a SV1000S. On the 14, I go one step colder (CR10EK) for nitrous use. The SV has these or one step hotter (CR8EK--which is what's spec'd for that motor), depending on which I had handy at the time. As per the ancient motoman site, these are good for 2hp on an inline 4, vs 'normal' plugs. Works for me. I have not pushed more than a 50 shot of nitrous past them, but don't forsee issues with the plugs so long as the ignition timing is kept in check. ## Features - 4 pack NGK Standard 4548 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 | B00M5EUYJQ | | Best Sellers Rank | #57,299 in Automotive ( See Top 100 in Automotive ) #443 in Automotive Replacement Spark Plugs | | Brand Name | NGK | | Compatible with Vehicle Type | Car, Truck | | Core Material | Copper | | Customer Reviews | 4.9 4.9 out of 5 stars (36) | | Included Components | 4548 | | Item Weight | 4.48 ounces | | Manufacturer | NGK Japan | | Manufacturer Part Number | 4548 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Thread Size | 14mm x 1.25mm | | Top Material Type | Ceramic | | UPC | 605349701139 | | Unit Count | 4.0 Count | ## Product Details - **Brand:** NGK - **Core Material:** Copper - **Thread Size:** 14mm x 1.25mm - **Top Material Type:** Ceramic - **Vehicle Service Type:** Car, Truck ## Images ![Spark Plug CR9EK- Set of 4 - Image 1](https://m.media-amazon.com/images/I/41D59pnNXSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Meet my need *by P***S on October 9, 2025* Great price and shipping time ### ⭐⭐⭐⭐⭐ As described *by A***B on July 16, 2025* Does what it says on the tin.
