Gold Plug Magnetic Oil Sump Drain Plug & Washer – MX-5 MK3 / NC (2005–2015) • MP-02

Gold Plug MP-02 Magnetic Oil Sump Drain Plug & Washer

Performance magnetic engine oil sump drain plug for Mazda MX-5 MK3 / NC 1.8L and 2.0L petrol models (2005–2015), including MK3, MK3.5 and MK3.75 variants.

The Gold Plug MP-02 is a direct-replacement magnetic oil drain plug designed to capture ferrous metal particles circulating through engine oil. Its high-strength neodymium magnet attracts and retains metallic debris, including fine particles that may pass through the engine's oil filtration system.

Manufactured from precision CNC-machined 303 stainless steel, the MP-02 incorporates a high-temperature N45SH neodymium magnet secured within the plug body. The plug can be removed, inspected and cleaned during routine engine oil changes.

The plug is fitted to the engine oil sump in place of the standard drain plug. One plug is required per vehicle, and this product is supplied with a sealing washer.

An excellent addition to routine servicing, engine maintenance and track-day preparation, the magnetic tip also allows collected ferrous debris to be inspected whenever the oil is changed.
