It was recommended I use these since they run a bit cooler...I have performance headers, a tune, and a cat back installed. So far so good! ### ⭐⭐⭐⭐⭐ C7 z06 one step colder plugs *by P***S on July 19, 2026* This is for C7 Z06 - one step colder. Need to gap it. Good for bolt on mods or pulley change on Lt4 engine. I know Amazon says this doesn't fit but they're wrong. Also, they wanted me to use ltr5ix plugs which is 2 steps warmer and wrong. ## Frequently Bought Together - (8-Pack) NGK Spark Plugs LTR7IX-11 (Stock # 6510) - Motorcraft FL-500S Oil Filter - 5w50 Ford Motorcraft XO-5w50-QGT Full Synthetic Motor Oil 12 qt case --- ## 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.sg/products/54303635-8-pack-ngk-spark-plugs-ltr7ix-11-stock-6510](https://www.desertcart.sg/products/54303635-8-pack-ngk-spark-plugs-ltr7ix-11-stock-6510) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-07*
