Description

Upgrade your Hyosung with this Stainless Steel Oil Filler Plug — now compatible with a wide range of models listed below!

📑 The standard OEM oil filler plug works, but it’s limited — usually requiring awkward pliers that can scratch or dent it. This premium stainless plug is a simple yet clever upgrade: use a proper hex bit, socket tool, or large Allen key instead!

🔧 Not just for looks…
This Oil Filler Plug is polished to a shine that suits black, grey, or chrome engines. It’s easy to remove, far more durable, and much harder to damage than the stock plug. A small upgrade that makes a big difference during oil changes!

🔧 Fitting Instructions: No tools needed — swap & go!
