AUTOEXE Ram Air Intake System for Mazda RX8 (Series 1 & 2, 2003-2012)

Replaces the full intake path with a matched ram air system, sharpening throttle response and bringing out the Renesis induction note.

Mazda RX8 ram air intake with carbon-fibre housing and exposed red filter

$1,680

The Mazda RX8 ram air intake from AUTOEXE replaces the entire factory intake path as one coordinated system. It suits Series 1 and Series 2 owners who want a genuine upgrade, not a piecemeal collection of parts. Air is drawn from a dedicated duct at the front of the bumper, then channelled through a large-capacity cleaner box with a specially designed intake path.

Filtration comes from a K&N wet-type element, supplied with a cleaning and maintenance kit. The intake pipe length and inner diameter are optimised for strong, progressive pull from the moment the accelerator moves. High-grade carbon insulation on the main body keeps incoming air cool and dense. According to AUTOEXE’s own design brief, the result is an improvement in fuel efficiency and torque within the stock ECU’s air-fuel correction margin.

Mazda RX8 Ram Air Intake Key Features

  • Front-bumper air ducting draws in fresh, cool air from outside the engine bay rather than recirculating warm underbonnet air.
  • The system ships with a K&N wet air filter and a full maintenance kit. Servicing the element requires no specialist tools or consumables.
  • Original sensors slot straight in. The factory MAF sensor is retained without modification, keeping ECU fuelling accurate from the first start.
  • Carbon-insulated bodywork and optimised pipe geometry deliver strong mid-range pull and progressive top-end acceleration.
  • Finally, the red finish gives the engine bay a purposeful, deliberate look that matches the quality of the engineering underneath.

For RX8 enthusiasts, the Mazda RX8 ram air intake is most rewarding on cars where the factory airbox has never been refreshed. Throttle response sharpens noticeably, and the induction note becomes more defined through the rev range.

It is audible inside the cabin, yet remains genuinely sporty rather than intrusive. It is an upgrade you hear and feel every time you drive.

Pair this intake with the AUTOEXE Intake Suction Kit to extend the coordinated intake system further. If your MAF sensor has high kilometres, fitting the GENUINE MAZDA OEM MAF Sensor at the same time keeps the Mazda RX8 ram air intake working with a correctly calibrated air-flow reading. The HKS Hi-Power Cat-Back Exhaust with Titanium Tip complements an intake upgrade well, freeing the exhaust side to match what the induction gains. Full details on AUTOEXE’s engineering approach are on the AUTOEXE official website.

Frequently Asked Questions

Does the AUTOEXE ram air intake fit both Series 1 and Series 2 RX8 models?

Yes, the AUTOEXE Ram Air Intake System is designed to suit both Series 1 (2003-2008) and Series 2 (2009-2012) RX8 models as a complete matched system.

Will fitting this intake require a remap or ECU tune?

No remap is required. The AUTOEXE ram air intake retains compatibility with the factory MAF sensor arrangement, so the original air-flow measurement stays intact without any modification or mapping changes.

Does this replace the entire factory airbox and intake path, or just part of it?

It replaces the full intake path as a single matched system, not individual components. This eliminates the fitment inconsistencies that can come from mixing parts from different sources.

Will my original sensors fit the AUTOEXE intake without modification?

Yes. The original factory sensors integrate directly into the AUTOEXE ram air intake system with no modification required.

What difference will I actually notice after fitting this intake?

Throttle response sharpens noticeably, and the rotary induction note becomes more defined through the rev range. The improvement is felt most clearly when climbing toward the redline, where the Renesis engine's mechanical character comes through more clearly.

Is this intake most beneficial on higher-kilometre cars with the original airbox?

Yes. The AUTOEXE ram air intake makes the most noticeable difference on RX8s where the factory airbox has never been replaced, as an aged or restrictive original assembly is what the system is effectively replacing.

What colour is the AUTOEXE ram air intake?

The intake system is finished in red, giving the engine bay a purposeful AUTOEXE accent that complements a performance-focused build.

Should I replace my MAF sensor at the same time as fitting this intake?

If your RX8 has high kilometres on the original MAF sensor, fitting a new genuine Mazda OEM MAF sensor alongside the AUTOEXE intake is a worthwhile combination. It ensures the intake system is working with a correctly calibrated air-flow reading from day one.
