The RX8 panel air filter from GREDDY TRUST’s AIRINX-GT range is a direct-fit replacement element for the Renesis factory airbox. It suits every Series 1 and Series 2 model from 2003 to 2012.

A special high-performance fibre media improves intake efficiency over a standard flat panel element. The whole swap happens without modifying the airbox, re-routing any ducting, or touching the MAF sensor calibration.

GREDDY TRUST AIRINX-GT RX8 Panel Air Filter Features

  • Direct-fit installation seats the element precisely inside the factory airbox. No additional hardware or remapping is required.
  • High-performance fibre media with a pleated design increases effective filtration area. This RX8 panel air filter lets the Renesis draw cleaner air with less restriction than a worn or standard element allows.
  • A steel net laminate provides structural rigidity, holding the media firmly in shape under sustained airflow and preventing distortion at high revs.
  • Precision-moulded rubber edges deliver a dust-tight perimeter seal against the airbox housing. This blocks contamination that a degraded OEM element can allow through gaps over time.
  • Finally, the AIRINX-GT offers outstanding cost performance: a genuine GREDDY TRUST component developed in Japan and trusted by RX8 owners across Australia.

For RX8 enthusiasts, the most immediate benefit shows up climbing toward the Renesis rev ceiling. A clean, unrestricted element keeps charge air flowing freely. The OEM airbox sits undisturbed, and the MAF sensor continues reading exactly as Mazda intended.

It is the cleanest possible intake refresh at a service visit. The value compounds if the existing filter has never been changed.

A fresh RX8 panel air filter works best when intake air is measured accurately. The GENUINE MAZDA OEM MAF Sensor is a natural companion, keeping intake volume data precise. You can keep filtration components from the same manufacturer. The GREDDY TRUST Oil Filter (Series 1) and GREDDY TRUST Oil Filter (Series 2).

Together they round out a consistent GREDDY TRUST service kit. Owners who want to go further can explore the AUTOEXE Intake Suction Kit. It builds on a clean-filtering airbox with an optimised intake path. Full product details are available through the official GREDDY TRUST site.

Frequently Asked Questions

Does this filter fit both Series 1 and Series 2 RX8 models?

Yes, the GREDDY TRUST AIRINX-GT is a direct-fit replacement for all RX8 models from 2003 through to 2012, covering both Series 1 and Series 2. It seats inside the factory airbox without any modification to the airbox or intake pipework.

Do I need to remap or retune the RX8 after fitting this filter?

No remap is required. The AIRINX-GT drops straight into the factory airbox and retains the original intake layout, so the MAF sensor calibration remains intact and the ECU sees no change to the intake configuration.

How does the double-pleated media differ from a standard flat panel filter?

The double-pleated fibre construction increases the effective filtration surface area compared with a standard flat panel element, allowing stronger airflow to reach the Renesis engine while still capturing contaminants across a larger media area.

Will the filter seal properly inside the airbox to prevent unfiltered air getting through?

Precision-moulded rubber edges run around the perimeter of the AIRINX-GT element and form a dust-tight seal against the factory airbox housing, preventing contamination from bypassing the filter media at the edges.

Does the filter hold its shape under high airflow conditions?

A steel net laminate is bonded to the media to provide structural rigidity, keeping the element from collapsing or deforming under sustained airflow through the intake system.

How difficult is installation, and are any tools or modifications needed?

Installation is straightforward and requires no airbox modifications, re-routing of intake pipework, or specialist tools. The AIRINX-GT is designed as a service-interval drop-in replacement, making it a clean swap at a standard filter change.

Is this a washable and reusable filter, or a disposable element?

The verified product information does not confirm whether the AIRINX-GT is washable and reusable or a disposable element. Check the product packaging or contact GREDDY TRUST directly for maintenance guidance specific to this filter.

Are there any companion parts worth fitting at the same service interval?

A genuine Mazda OEM MAF sensor benefits directly from a clean, unrestricted filter element since it measures intake air volume accurately. The GREDDY TRUST oil filters for Series 1 and Series 2 are also natural companions if you prefer to keep filtration components from the same manufacturer.
