Performance Air Intake for Mazda RX-8 2004-2011 1.3L

Optimize Airflow and High-RPM Breathability for your Mazda RX-8 Renesis 13B-MSP

Who It’s For: Designed specifically for 2004-2011 Mazda RX-8 owners running the naturally aspirated Renesis 13B-MSP rotary engine.

The Problem: The Renesis 13B-MSP is a high-revving masterpiece that lives for the 9,000 RPM redline, but the factory air box is a major bottleneck. The stock plastic piping is designed for sound dampening rather than flow velocity, causing the engine to struggle for air during peak power bands and increasing the risk of heat soak in the cramped RX-8 engine bay.

The Solution: We engineered this intake to eliminate the restrictive baffles of the stock system, delivering a straight-shot path for oxygen to reach the rotors. By providing a higher volume of air, this kit helps the Renesis maintain its torque curve longer while sharpening throttle response every time you blip the pedal for a downshift.

Why This is the Ultimate Upgrade

• Rotary-Tuned Induction: Expect a proven gain of 5-8 horsepower and 5-8 lb-ft of torque, specifically felt in the mid-to-high RPM range where the RX-8 performs best.
• Dry-Flow Technology: Includes a high-flow, washable, and reusable air filter. This is a dry-media filter, meaning you won’t have to worry about oil fouling the sensitive Mass Air Flow (MAF) sensor—a common issue on these cars.
• Aggressive Acoustic Note: Swapping the factory box for this open-element design transforms the engine note into a deep, mechanical growl that reflects the unique nature of the rotary engine.
