Fitment Notes

• This filter fits all RX-8 variants across the full production run (2003-2011 US; 2003-2012 some international markets), covering both 4-port (189 hp) and 6-port (232 hp) versions of the 13B-MSP Renesis engine
• US model years run 2004-2011; 2003 is the Japanese/international first model year - fitment confirmed for all chassis codes SE3P
• Series II RX-8 (2009-2011) received minor engine management revisions but uses the same airbox and this same filter
• The R2 1.3L designation refers to the twin-rotor Wankel displacement - not a conventional piston engine; this filter is purpose-built for the RX-8's unique airbox
• Does not fit the Mazda RX-7 - that model uses completely different airbox architecture

• 4-layer oiled cotton gauze media for high airflow and reliable contaminant capture
• Engineered to increase horsepower and high-RPM performance over stock paper filters

Product Description

The K&N 33-2284 is a washable, reusable drop-in replacement air filter purpose-built for the Mazda RX-8 (2003-2011) and its unique 13B-MSP Renesis twin-rotor Wankel engine. Covering both the 4-port (189 hp) and 6-port (232 hp) variants across all trim levels and transmission options, this filter drops directly into the factory airbox without modification and is fully compatible with OEM MAF sensors. The Renesis engine's high-RPM character - with a 9,000 RPM redline - makes improved airflow particularly impactful, and the K&N 33-2284 is engineered to deliver exactly that.

Only needing cleaning every 75,000 miles, the K&N 33-2284 is a natural lifetime upgrade for RX-8 owners who want a cost-effective, reusable alternative to disposable OEM paper filters. Whether running a standard 4-port automatic or a high-output 6-port manual, this filter delivers improved airflow and throttle response across the 13B-MSP rev range without voiding the factory warranty.
