K&N Cold Air Intake Kit for 2003-2011 MAZDA (RX-8)

K&N air intake systems are engineered for increased performance, outstanding durability, and sleek aesthetics, and are available in a variety of finishes and powder coatings. K&N's state-of-the-art High-Flow Air Filter helps to shield your engine from contaminants, while a meticulously engineered aerodynamic tube design contributes to a guaranteed increase in horsepower and torque. K&N air intake systems are designed to improve acceleration, towing, and throttle response while providing world-class protection for your engine. Our intakes are dyno-tested and provide more airflow compared to OEM intake systems.

K&N intakes are easy to install and maintain, with air filter cleaning required only every 100,000 miles. The replacement air filter, RU-5123, is designed for the 2003-2011 MAZDA RX-8. K&N's cold air intake systems provide a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into your engine, resulting in an estimated increase of up to 11HP and up to 7 ft.lbs. of Torque. The intake systems allow your engine to breathe and sound as it should, with a growl on acceleration and a return to quiet once at speed.

K&N's air intake horsepower/torque testing is performed on wheel-based dynamometers, and the reports are included with each intake system. The signature, reusable air filter combines 4 layers of pleated, breathable cotton with K&N's red filter oil to absorb dirt and dust particles, allowing clean air to continue flowing into your engine, and only needing cleaning every 100,000 miles under normal highway driving conditions.

The durable aluminum intake tube and custom heat shield provide a more custom look under the hood, with the mandrel-bent and powder-coated aluminum intake tube helping to increase the volume of airflow to your engine, and the heat shield protecting the intake air from the high temperature of your engine bay. K&N air intake systems will not void the manufacturer's vehicle warranty, and are backed by a No-Hassle Lifetime Limited Warranty, protecting them for the life of your vehicle.

The entire air intake system can typically be installed in less than 60 minutes with basic hand tools, using the detailed, step-by-step instructions and all necessary parts. K&N air intake systems are proudly made in the USA, ensuring trusted quality and reliability, and are backed by US-based customer support.
