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

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.

Common Questions

Will this intake fit my 2004-2011 Mazda RX-8?
Yes, this performance air intake is engineered specifically for all 2004-2011 Mazda RX-8 (SE3P) models equipped with the naturally aspirated 1.3L Renesis 13B-MSP rotary engine.

Does the air filter require oil when servicing?
The included high-flow filter uses washable and reusable dry-flow media, so it does not require oil and protects the sensitive Mass Air Flow (MAF) sensor from oil fouling.

What kind of performance gains can I expect?
By replacing the baffled factory airbox with a straight-shot airflow path, this system delivers a proven gain of 5-8 horsepower and 5-8 lb-ft of torque in the mid-to-high RPM range.

What tools are needed for installation?
This kit is designed as a direct-fit upgrade for the SE3P chassis and installs using simple hand tools.

How will this intake change the sound of my RX-8?
Switching from the sound-dampened factory airbox to this open-element design gives the rotary engine a deeper, more aggressive mechanical growl under acceleration.
