I can only find 5/8 inch and larger.** A: Unless these are somehow the tiniest spark plugs in existence, you do not need a 3/8” socket. 5/8” will be the correct socket size and 3/8” will be the size of the ratchet attachment on the other end of the socket. 3/8” is about 10 mm which is smaller than the threads on this plug. **Q: will this fit 2004 dodge ram 1500 4.7 liter 4x4 v8?** A: No, these Autolite XP3923 spark plugs fit 2002-2005 Dodge Ram 1500 (3.7L). Autolite XP5224 will fit 2002-2007 Dodge Ram 1500 (4.7L V8). **Q: Will these spark plugs fit 2003 Altima 2.5** A: Hello, no these will not fit a Altima. Ngk are the original part number 6240. Please let us know if we can be of further assistance. **Q: Where are these made?** A: Autolite Iridium XP spark plugs are designed and engineered in the USA. However, they are manufactured in China - as are all Autolite spark plugs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good deal *by H***E on 16 November 2024* ### ⭐⭐⭐⭐⭐ the right plug *by R***T on 26 November 2023* ### ⭐⭐⭐⭐⭐ مناسبة لMG ZS 2019 1.5 *by K***D on 1 February 2026* ممتازة جدًا ومجربها على عدة سيارات وبعضها مشيت عليها ممشى يتجاوز الثمانين الف بدون مشاكل ## Frequently Bought Together - Autolite Iridium XP Automotive Replacement Spark Plugs, XP3923 (4 Pack) - 4PCS Ignition Coils for 2002 2003 2004 2005 2006 2007 2008 2009 2.4L Toyota Camry Matrix RAV4 Solara Highlander Scion TC xB Lexus HS250h 2.4 Coil Packs OE# UF333 C1330 90919-02244 - FEL-PRO VS 50530 R Engine Valve Cover Gasket Set for Toyota Camry --- ## 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.com.au/products/399799888-xp-xtreme-performance-spark-p](https://www.desertcart.com.au/products/399799888-xp-xtreme-performance-spark-p) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-05-23*
