Periodic replacement helps maintain the engine’s performance. **Q: What are signs spark plug wires should be replaced?** A: Common signs of wear can include a rough-running engine, possible misfires and even hard starting. Acceleration can be affected and fuel economy can decline. Visually, cracks or fraying of the wires are signs replacement is needed. **Q: Are all spark plug wires the same?** A: No. Material composition and design can vary widely, resulting in varying levels of conductivity, durability and electrical interference suppression. GM Genuine Parts and ACDelco Gold Spark Plug Wires meet GM factory specifications. **Q: Do battery cables need to be replaced often?** A: Generally, battery cables don't need periodic replacement, but they are subject to corrosion and other forces of wear that can affect their performance. This is especially true in climates of high humidity, where the roads are salted in the winter. **Q: What are signs of the battery cables need to be replaced?** A: If loose connections are ruled out, hard starting, a failure to start and other intermittent electrical issues are common signs the battery cables should be checked for corrosion and other signs of wear. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by R***T on August 27, 2026* Good price..great quality..it's gm ### ⭐⭐⭐⭐⭐ Works Great *by J***R on June 28, 2026* Works as expected in my Chevy S10 ### ⭐⭐⭐⭐⭐ 2006 trailblazer LS fits powertrain and starter 100% happy *by D***C on February 2, 2026* 2006 trailblazer LS 4.2L fit perfect for the powertrain and the starter bought 2 replaced both at same time bought dec 9th 2024 2/2/26 still running great would buy again ## Frequently Bought Together - General Motors 13503102 Gray Multi-Purpose Relay - ACDelco GM Original Equipment 13500114 Multi Purpose Relay - GM Genuine Parts 15-81106 Multi-Purpose Relay --- ## 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.co.za/products/78905895-gm-genuine-parts-13503102-gray-multi-purpose-relay](https://www.desertcart.co.za/products/78905895-gm-genuine-parts-13503102-gray-multi-purpose-relay) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-11*
