Featuring copper cores for superior heat transfer, machine-rolled 14mm threads for durability, and a shorty design to prevent header damage, these plugs deliver instant throttle response, improved fuel economy, and reduced misfires—making them a top choice for enthusiasts seeking reliable, efficient upgrades. ## Description ACCEL's "Shorty" spark plugs keep your spark plug boots from being burned and your headers from being dented if you don't have enough room between your plug boots and your exhaust manifold or headers. Designed for trouble-free installation and removal in cramped spaces, these high-performance plugs are much easier than OE plugs to get a socket on but still deliver a larger, hotter, fuller flash front and significantly more power at high rpm. You'll have instant throttle response and better fuel economy with less fouling, flame dissipation, and misfire. These copper-core plugs provide increased thermal conductivity, come with machine-rolled 14mm threads to protect your heads, use a standard 5/8 socket, and come in a pack of eight. ## Features - Ideal for use in cramped spaces - Deliver significantly more power at high RPM - Instant throttle response and better fuel economy - Less fouling flame dissipation and misfire - Pack of eight ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BW8NYC | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #24,663 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Performance Spark Plugs | | Brand | ACCEL | | Brand Name | ACCEL | | Compatible with Vehicle Type | Vehicle | | Core Material | Copper | | Customer Reviews | 4.6 out of 5 stars 225 Reviews | | Global Trade Identification Number | 00042511181984 | | Item Weight | 0.55 Pounds | | Manufacturer | Accel | | Manufacturer Part Number | 8198 | | Model Number | 8198 | | OEM Equivalent Part Number | 8198 | | Thread Size | 14mm | | Top Material Type | Alloy Steel | | UPC | 042511181984 | | Unit Count | 8.0 Count | | Vehicle Service Type | Vehicle | ## Product Details - **Brand:** ACCEL - **Core Material:** Copper - **Thread Size:** 14mm - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** Vehicle ## Images ![ACCEL 8198 Performance U-Groove Header Spark Plug - Pack of 8 - Image 1](https://m.media-amazon.com/images/I/719sVQweLvL.jpg) ![ACCEL 8198 Performance U-Groove Header Spark Plug - Pack of 8 - Image 2](https://m.media-amazon.com/images/I/81LSy3qIiLL.jpg) ![ACCEL 8198 Performance U-Groove Header Spark Plug - Pack of 8 - Image 3](https://m.media-amazon.com/images/I/71kewrKZXVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***N on January 30, 2026* ### ⭐⭐⭐⭐⭐ Review *by W***. on February 27, 2026* ### ⭐⭐⭐⭐⭐ Review *by C***R on January 24, 2026* ## Frequently Bought Together - ACCEL 8198 Performance U-Groove Header Spark Plug - Pack of 8 - SHINEHOME Spark Plug Wire Heat Shield Sleeve 2500° Spark Plug Boot Protector Wire Boots Wrap for SBC BBC 350 454 8PCS Spark Wire Plug Covers - JDMSPEED New 10.5mm Spark Plug Wire Set Replacement for HEI SBC BBC 350 383 454 Electronic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/13435996-accel-8198-performance-u-groove-header-spark-plug-pack-8](https://www.desertcart.tw/products/13435996-accel-8198-performance-u-groove-header-spark-plug-pack-8) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-16*
