Its anti-vibration short outer electrode design and Thermal Edge ceramic insulator actively reduce carbon buildup, preventing misfires and extending lifespan. Compatible with rotary and standard car engines, this universal-fit spark plug is engineered in Japan to deliver reliable, high-performance starts every time. ## Description Specifications 0.6mm Iridium Alloy Center Electrode Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability. Outer Electrode with Platinum Chip The Outer Electrode incorporates a square platinum chip which improves urability, and when combined with the iridium center electrode boosts ignition performance. The Outer Electrode features a shortened tip design and tapered shape while maintaining the necessary space for proper ignition. Short Type Outer Electrode (Anti-Vibration) The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves longevity of the outer electrode. Thermal Edge After long idling or various combustion conditions carbon buildup can occur causing misfires. The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits. Spark Support Gap Discharges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup. ## Features - Heat Range 9 - HKS Spark Plug - For Rotary Apps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003THZK5Q | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #10,834 in Automotive ( See Top 100 in Automotive ) #40 in Automotive Performance Spark Plugs | | Brand Name | HKS | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Customer Reviews | 4.6 4.6 out of 5 stars (132) | | Gap Size | 0.6 Millimeters | | Global Trade Identification Number | 04957266720431 | | Included Components | Main component only | | Item Weight | 10 Grams | | Manufacturer | HKS | | Manufacturer Part Number | 50003-M40G | | Model Number | 50003-M45XL | | Number of Items | 1 | | OEM Equivalent Part Number | 50003-M45XL | | Thread Size | Fourteen millimeters by Nineteen millimeters | | Top Material Type | Metal | | Unit Count | 1 Count | ## Product Details - **Brand:** HKS - **Core material:** Iridium - **Thread size:** Fourteen millimeters by Nineteen millimeters - **Top material type:** Metal - **Vehicle service type:** Car ## Images ![50003-M45XL M-Series Super Fire Racing Spark Plug - Image 1](https://m.media-amazon.com/images/I/61Cyvw3gWLL.jpg) ## Questions & Answers **Q: Can it be used for honda accord 2011** A: Seems like yes.
