The integrated ceramic hotend with the hardened steel 0.4mm nozzle is a big step up from the stock setup. Installation was simple and straightforward, and everything fit perfectly without modification. The heating block design keeps temperatures stable, and the hardened steel nozzle is excellent for handling not just standard PLA and PETG, but also abrasive filaments like wood or carbon fiber without wearing out quickly. The included silicone sock is a nice bonus that helps maintain even heat and reduces filament buildup on the nozzle. So far, my prints have been clean, consistent, and I’ve noticed fewer clogs compared to the stock hotend. Definitely a solid upgrade for anyone looking to get better performance and longevity out of their Kobra S1 or S1 Combo. ## Frequently Bought Together - ANYCUBIC Kobra Hotend 3D Printer Extruder Hotend V5 J-Head Print Head with Silicone Sock 0.4mm Nozzle 24V ONLY Suit for Kobra,NOT Work with Kobra GO,Kobra Neo,Kobra Max,or Kobra Plus - LANKEGU 10PCS Brass Nozzles for Anycubic Kobra 2, 3D Printer Parts 10PCS 0.4mm Nozzles Kit for Kobra 2, Kobra 2 Neo, Kobra 2 Pro, Kobra 2 Plus, Kobra 2 Max --- ## 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.vu/products/443752330-upgrade-kobra-s1-ceramic-hotend-0-4mm-hardened-steel-nozzle](https://www.desertcart.vu/products/443752330-upgrade-kobra-s1-ceramic-hotend-0-4mm-hardened-steel-nozzle) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
