Anodized Magnetic Oil Filler Cap Plug Bolt – GT125R GV125 GT125 Hyosung

Description

The stock filler cap does the job, but it offers zero engine protection. This **Anodized Magnetic Oil Filler Cap** is a premium upgrade that offers both function and style, protecting your valuable 125cc engine from internally circulating metallic debris.

Made from high-grade aluminum, this cap won’t rust and is designed for easy removal with a standard spanner during oil changes—a small convenience that makes maintenance less frustrating.

💡 Why the Magnet Matters:

Every engine produces tiny metallic shavings from clutch wear and gear mesh. These microscopic bits can circulate in the oil system. The powerful magnet in this cap catches them before they cause further wear.

• 1️⃣ The Magnetic Core: Helps keep engine oil cleaner by catching metallic debris the filter might miss.
• 2️⃣ Tough Finish: Corrosion-resistant anodized aluminum that won’t fade or pit.
• 3️⃣ Workshop Friendly: Spanner/Socket removal point makes life easier in the garage.

🛠 Install Tips & Maintenance Guides

Installation is a direct swap. Use these tips for a perfect fit:

• 🧼 Wipe the filler neck area clean before fitting to avoid dirt entering your engine.
• 🛢 Lightly oil the O-ring before installation to ensure a good seal.
• 🔍 When removing the cap, check the magnet for debris—fine shavings are normal, chunks are not.
• ⚖️ Hand-tighten firmly only. Aluminum threads on your clutch cover do not like excess force.
