Designed for quick starts, better fuel economy, and smooth acceleration, it’s a trusted replacement spark plug backed by decades of Autolite expertise. ## Description Autolite Copper Core Spark Plugs deliver quick starts, good fuel economy, and smooth acceleration. The copper-glass seal bonds insulator and terminal post center electrode together to ensure full required voltage at spark gap, creating a gas-tight seal that is 100 percent leak-proof. Copper Core spark plugs feature a cold-formed steel shell and precision rolled threads, and a one-piece terminal post that adds strength. The multi-rib insulator reduces the danger of "flash-over" to prevent misfires, and the resistor reduces radio frequency interference (RFI) and electrode erosion. The full copper core electrode provides better performance in all conditions. Autolite Copper Core plugs are your industry standard. ## Features - MAXIMUM PERFORMANCE: Every Copper Spark Plug has a full copper core electrode which provides higher thermal conductivity for better performance in all conditions - IMPROVED DURABILITY: All Autolite spark plugs are Leak proof and come with a heat fused internal seal for long lasting durability - CONSTRUCTION: These replacement spark plugs have a copper-glass seal which bonds the insulator and the terminal post center electrode together - FUEL EFFICIENCY: The Autolite copper automotive replacement spark plug are guaranteed to deliver quick starts, better fuel economy and smooth acceleration - AUTOLITE ADVANTAGE: Since 1936, Autolite has been a trusted leader and innovator in spark plug technology. You can count on our copper plugs for performance and value, backed by decades of experience and passion ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CSKKX2 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #792,372 in Automotive ( See Top 100 in Automotive ) #3,988 in Automotive Replacement Spark Plugs | | Brand Name | Autolite Iridium Ultra | | Compatible with Vehicle Type | Motorcycle | | Core Material | Copper | | Customer Reviews | 4.6 4.6 out of 5 stars (123) | | Global Trade Identification Number | 00009100252692 | | Included Components | Spark Plug | | Item Type Name | Spark Plug | | Item Weight | 8 ounces | | Manufacturer | FRAM | | Manufacturer Part Number | 458 | | Manufacturer Warranty Description | Lifetime Limited Warranty | | Model Number | 458 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | 458 | | Thread Size | 14mm | | Top Material Type | Alloy Steel | | UPC | 009100252692 | | Unit Count | 1 Count | ## Product Details - **Brand:** Autolite Iridium Ultra - **Core Material:** Copper - **Thread Size:** 14mm - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** Motorcycle ## Images ![Autolite 458 Copper Non-Resistor Automotive Replacement Spark Plug (1 Pack) - Image 1](https://m.media-amazon.com/images/I/61fZ640fn3L.jpg) ## Available Options This product comes in different **Number Of Items** options. --- ## 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.pt/products/39729688-autolite-458-copper-non-resistor-automotive-replacement-spark-plug-1](https://www.desertcart.pt/products/39729688-autolite-458-copper-non-resistor-automotive-replacement-spark-plug-1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-20*
