An RX8 magnetic drain plug is a direct, high-value swap that makes every gearbox service more informative. This R-MAGIC unit replaces the standard plug with a super-strength magnet. It pulls ferrous particles out of suspension in the gearbox oil before they can circulate and cause wear. Fits all RX8 models from 2003 to 2012.

R-MAGIC RX8 Magnetic Drain Plug Features

  • Super magnetic core attracts ferrous particles that circulate in gearbox oil between service intervals.
  • Retained debris sits on the plug face, giving you a visible wear read at every drain before the old oil is discarded.
  • Suits every RX8 across the full production run, both Series 1 and 2 models, 2003 to 2012.
  • The black finish delivers a clean, discreet look that suits any underbody presentation.
  • Finally, the direct-replacement design means no modification needed. Thread it in, torque it down, done.

For RX8 enthusiasts, the real value shows up at service time. Inspect what the magnet has collected, clean it off, and reinstall. Fine metallic dust is normal wear. Heavier particles are a prompt to investigate further. Over successive changes, you build a picture of exactly how your gearbox is tracking.

Pair this Mazda RX8 magnetic drain plug with fresh lubricant. The CUSCO Super Sports Gearbox Oil with Neo 2L is the natural companion, putting clean, purpose-formulated oil back in once the old fluid and its debris are out. For a broader lubrication service, the GREDDY TRUST Super Magnetic Oil Pan Sump Plug extends the same debris-capture discipline to the engine sump. Learn more about the manufacturer at R-MAGIC.

Frequently Asked Questions

Which RX8 models does the R-MAGIC magnetic drain plug fit?

The R-MAGIC Super Magnetic Gearbox Drain Plug fits all RX8 Series 1 (2003-2008) and Series 2 (2009-2012) models across the full production run, so there is no need to check which generation you have before ordering.

Does fitting this magnetic drain plug require any modifications to the gearbox?

No modifications are required. The R-MAGIC plug is a direct replacement for the standard gearbox drain plug - thread it in and torque it down. No drilling, tapping or additional hardware is involved.

What does the magnet actually capture, and how do I read what it collects?

The super-strength magnet attracts ferrous particles that circulate in the gearbox oil between service intervals. At each drain, inspect the debris on the plug face before discarding the used oil. Fine metallic dust is consistent with normal wear; heavier or more substantial particles are a prompt to investigate the gearbox further.

How often should I check and clean the magnetic drain plug?

Clean and inspect the plug at every gearbox oil change. Wipe the debris off the magnet face, assess what was collected, then reinstall. Over successive services you build a reliable picture of how your gearbox is tracking over time.

Does the standard OEM drain plug have a magnet?

The standard RX8 gearbox drain plug does not incorporate a magnet, so ferrous wear particles remain suspended in the oil and are simply drained away with it. The R-MAGIC plug captures that debris and makes it visible, turning a routine service into a useful condition check.

What gearbox oil is recommended to use with this plug?

Once the old fluid and its captured debris are out, CUSCO Super Sports Gearbox Oil with Neo 2L is a well-matched companion, putting clean, purpose-formulated lubricant back into the gearbox alongside the upgraded drain plug.

Can I use the same debris-capture approach for the engine sump as well?

Yes. The GREDDY TRUST Super Magnetic Oil Pan Sump Plug applies the same principle to the engine sump, so pairing the two extends debris monitoring across both the gearbox and the engine lubrication system in a single service routine.
