This RX8 intake suction kit replaces the factory rubber hose between the airbox and throttle body. It fits all Mazda RX8 models from 2003 to 2012. Where the OEM hose prioritises noise suppression and mass-production cost, AUTOEXE’s multilayer polyester silicone construction is built to maximise effective intake flow. The result is better resistance to deformation under the significant negative pressure a rotary engine generates at full throttle.
For RX8 enthusiasts, the intake note takes on a more urgent character under hard acceleration. Throttle response from light inputs also feels more direct in everyday driving, not just at the top of the rev range. Fitting an RX8 intake suction kit improves both feel and presentation in a single, straightforward job.
Pair this kit with the GENUINE MAZDA OEM MAF Sensor if your mass air flow sensor is due for replacement. A known-condition sensor is worth sorting alongside any intake work. The AUTOEXE Brake Fluid Cap adds a matching red accent to complete the engine-bay presentation. Find the full AUTOEXE product range at the AUTOEXE official website.

Yes, the AUTOEXE Intake Suction Kit fits all Mazda RX8 models from 2003 to 2012, covering both Series 1 (2003-2008) and Series 2 (2009-2012). Series 2 owners should check whether their specific intake configuration requires any hose-port or block-off attention before fitting.
No. The AUTOEXE Intake Suction Kit is designed to work with the factory Mazda airbox retained in place. It replaces only the rubber hose between the airbox and throttle body, so the Renesis continues breathing through the OEM air filtration setup.
It is a direct drop-in fitment requiring no cutting or modification to the vehicle. The kit replaces the factory rubber hose at the same position in the intake tract across all RX8 models.
Both occupy the same position in the intake path and perform very similarly in practice according to store owner Josh. The main differences are material and finish: the KTS unit uses polished aluminium and suits a value-focused build, while the AUTOEXE kit uses red silicone and suits owners building a consistent AUTOEXE-branded engine bay.
The more direct hose path between the airbox and throttle body supports a sharper throttle feel, which is particularly noticeable from light to moderate inputs during everyday driving. Neither this kit nor comparable alternatives produces dramatic power gains on its own.
Silicone handles underbonnet heat more effectively than standard rubber and resists deterioration over time. The red finish also makes the upgrade immediately visible in the engine bay, distinguishing it visually from polished-aluminium alternatives.
ODULA ram-air ducting pairs naturally with this kit for a more complete intake refresh while keeping the factory airbox. If your mass air flow sensor is due for replacement, fitting a Genuine Mazda OEM MAF Sensor alongside any intake work ensures the sensor is in known-good condition.
