Injen 03-03.5 Mazdaspeed Protege Turbo Polished Cold Air Intake

Injen Technology is known for making well-built performance parts, and this RD Series cold air intake is a prime example for your 2004 Mazda Miata. If you're looking to add some easy horsepower and give your engine bay a cleaner look, this intake is a solid option. It's designed to pull cooler, denser air from behind the front bumper, which helps the engine breathe better and make more power.

The heart of this system is the smooth, mandrel-bent aluminum tubing. This design means there are no restrictions in the airflow path, allowing for a more efficient charge into the engine. In testing, this intake has shown gains of up to 14 horsepower and 14 lb-ft of torque, all while making sure your air-fuel ratios stay safe without needing a separate tune. You'll also notice a more aggressive, throaty sound when you step on the gas.

This kit includes a fully serviceable Injen SuperNano-Web dry air filter, which offers a large surface area for great airflow and reliable filtration. It's finished in a polished look to really make your engine bay stand out. Injen backs this intake with a limited lifetime warranty, and it's made right here in Pomona, California.
