Description
Tiny metal flakes are a hidden issue for high-revving engines. While your main oil filter cartridge catches the big grit bits, this magnetic sump bolt pulls in the incredibly fine metal dust that floats around inside your engine casing. By locking these shavings down at the lowest point of the oil pan, you stop them from scraping your internal bearings or blocking your oil pump lines. It is one of the cheapest and most effective upgrades you can give your GV300S to enjoy absolute peace of mind on everyday roads.

🔧 Install Tips
- Do Not Overtighten: Aluminium sump bolts need a careful, steady hand. Always use a proper torque wrench and tighten the bolt to the factory setting (usually around 20-25Nm) to avoid pulling the threads out of your soft engine cases.
- Clean the Magnet Tip: Every time you do an oil service change, use a clean garage cloth to wipe off the magnet. You will notice a small bit of dark metallic fuzz stuck to it—this is exactly what you are saving your motor from!
- No Liquid Sealants: Do not use thread-locking glue or silicone liquid gaskets on the bolt threads. The included aluminum or copper sealing washer is designed to sit flat and stop leaks all by itself.
