RX8 genuine Mazda parts are factory-made OEM components built to exact production specification. They are the definitive choice for owners maintaining, repairing or restoring their RX8 to original condition, delivering correct fitment, factory calibration and known-condition quality that a used or pattern alternative simply cannot guarantee.

OHLINS MAS-MI00S1 Road & Track Coilover Suspension for Mazda RX8 (Series 1 & 2, 2003-2012)
if you want it to handle the best possible on the street without it being harsh it's the way to go. It or Bilstein are the only thing I recommend for coil-overs other than pure race shocks. The B16/PSS9 is the only other one I'd recommend, but if you can afford it the nod goes to hlins.
I am happy with the mod. Very happy. Taka s recommended first mod list: Sway bar. Odula intake or similar. Brake pads.
AUTOEXE Lower Arm Bar (Rear) for Mazda RX8 (Series 1 & 2, 2003-2012)
The rear lower arm bar is very nice and strong. There are 4 pieces two triangular bars for the subframe and two smaller bars that strengthen the rear arm. Overall I'm very happy with the bars. The quality of the autoexe bars are excellant and the packaging and handling of the bars are superb. I found my turn in using the autoexe bar was more responsive then my old Cusco lower arm. As well my rear is more stable when exiting out of corners. The best part about these bars is probably the front member brace and the triangualar rear brace that strengthen up the chassis. Because with my current suspension setup to the max and without my roll cage installed yet, my cars chassis is flexing from the pressure and stress buildup that I put on it at the track. For the price I'm very satisfied. Even though the price isn't cheap and in some cases you can buy a car, but the bars are definatley worth the money.
RX8 Upgrades supplied Coils and Mounting Plate installed today
Just put my Greddy oil pan on this past week and switched from Royal Purple 5w20 to 5w30. On driving back & looking at my EGT's it is a good 30-40 degrees F cooler than before. Didn't think it would make much/if any difference, but it did. I'm pretty surprised, I guess the extra .5 Quart of oil and/or the aluminum design makes a bit of difference.
Finally have the chance to fit the RX8 Upgrades supplied AutoEXE brake rotors and pads to BADBEE On the weekend AutoEXE lines will be fitted to the front This is just the beginning I still have the rears to do but looking forward to feeling the braking difference once all is complete
When a repair calls for RX8 genuine Mazda parts, you remove the guesswork entirely. No wondering whether the calibration is close enough. No questioning whether the connector will seat properly. Also, no doubt about whether the material will hold up to the same stresses the original was designed for.
Factory specification is factory specification. For a car as specific as the RX8, that distinction matters. Mazda Australia engineers these components to exact production tolerances. Furthermore, that precision is what you are buying when you choose genuine over pattern.
The Renesis engine is a precision piece of engineering. It has tight tolerances and a sensitivity to anything outside its designed operating parameters. For example, sensors, solenoids and cooling components are calibrated for this specific application. A genuine Mazda RX8 MAF sensor reports airflow the way the ECU expects. Similarly, a genuine thermostat opens at the temperature the cooling strategy was built around. A rotary engine will let you know when something is outside spec. Therefore, choosing RX8 genuine Mazda parts rules that out entirely.
The same principle applies to mechanical and fastening hardware. For instance, OEM wheel nuts are threaded and finished to Mazda’s own standard. They seat correctly against the hub. As a result, they maintain the clamping load the engineers specified. Details like that compound across a complete car.
A used OEM part may look correct and may even function correctly. However, its wear state, service history and remaining service life are unknowns you absorb into your car. In contrast, a new factory-genuine component arrives at zero hours. Its calibration and material integrity are intact. Furthermore, it is ready to perform exactly as designed from the moment it is fitted.
That is a meaningful difference for anything safety-related or central to engine management. In addition, it is worth noting that RX8 genuine Mazda parts are not unlimited in supply. As production ends, some become progressively harder to source.
Finally, for owners in Australia searching for Mazda RX8 OEM components, buying new now is simply sound forward planning. Browse the range above and confirm the correct part number for your specific repair before ordering, particularly where multiple related sensors or solenoids are fitted to the same system.
Many genuine Mazda parts for the RX8 remain available new, though supply of some components does tighten over time as production runs end. Sourcing a new OEM part now is worth considering when an original component has worn or failed, rather than waiting until availability becomes uncertain.
A new genuine part gives you a known starting point - correct factory calibration, full service life remaining, and no unknown wear or history. A used OEM part from a donor car may look identical but carries uncertainty about how it was treated, stored or why it was removed.
Yes. Genuine Mazda components are made to the original factory specification for the RX8, so fitment, calibration and material quality match the application exactly. This is particularly relevant for precision items such as sensors, cooling components and engine-management hardware where an incorrect fit creates problems.
Common genuine replacement items for the RX8 include fuel pump components, mass air flow (MAF) sensors, thermostats, intake solenoids, OEM wheel nuts and short motor assemblies. For any component where correct calibration or factory fitment directly affects engine or drivetrain reliability, genuine is the straightforward choice.
The RX8 engine-management system is calibrated around the factory MAF sensor's output characteristics. A genuine Mazda replacement restores that original calibration exactly, which matters for idle quality, throttle response and fuel mapping accuracy. Aftermarket alternatives vary in how closely they match the OEM signal.
Yes, and for many functions it makes sense to do so even on a modified car. Components such as cooling parts, sensors and fasteners perform a specific role that benefits from factory accuracy regardless of what else has been changed. Genuine parts are a reliable foundation that supports further modifications cleanly.
The RX8 was sold in Series 1 and Series 2 variants with differences in engine specification, sensors and ancillary components, so confirming your series and the specific part required before ordering is important. Where multiple related sensors or solenoids are fitted, identifying the exact failed component first avoids ordering the wrong item.
