Miata High Flow Air Intake - 1999-2005 Miata (Non-turbo)
A classic MIata intake and a proven performance upgrade! 1000's sold!
In late 2021 we made the difficult decision to find an alternate casting source for the aluminum duct that is included in our kit. We've since transferred all tooling to a new casting shop and used this new opportunity to address issues to improve manufacturing efficiency and product appearance. After several weeks of upgrading, prototype testing and modifications this duct is now in the their production schedule with a delivery date of late February! Once we received the ducts it should take approximately 2+ weeks to machine and polish the ducts in-house at Racing Beat.
The Miata High Flow Air Inlet Kit for the 1999-05 Miata (non-turbo) combines the advantages of a low restriction, reusable K&N air filter with a smoother air passage into the factory air meter assembly to improve airflow. Designed and engineered by Racing Beat, this attractive assembly, with its polished aluminum casting, positions the genuine K&N air filter element in the area behind the headlamp.
For models equipped with the factory shock tower brace, we offer the optional Shock Tower Brace Mounting Bracket for 1999-00 Miatas or 2001-05 Miatas (shown on the car above). This bracket can be used to retrofit the shock tower brace for use with the High Flow Intake Kit. However, this brace can also be removed entirely, eliminating the need to obtain the optional mounting bracket.
With the second generation Miata, it is apparent that Mazda engineers put some effort into directing fresh air into the engine compartment. The engineers have tried to route air through the wheel well area and up through the sheet metal body panels. The stock air-box snorkel is positioned over an opening in the engine compartment body panel to take advantage of the improved airflow.
The High Flow Air Inlet Assembly replaces the stock air box and positions the air filter over this body panel opening. Not only does this unit look great, but the sound of the air rushing through the inlet tube gives the Miata a decidedly more aggressive sound!
Performance & Dyno Charts
Our dyno tests of this air intake assembly showed gains of an additional 6 HP gain over the stock intake. This intake increased horsepower from 110 to 116 on our dyno runs, with a slight improvement in mid-range torque. To view a graph of the dyno test results, click here.(PDF)
Are you required to keep your car emissions legal? Is your car required to pass a tailpipe emissions test? The Racing Beat High Flow Intake Assembly has received an emissions exemption (E.O. D-450-6) from the California Air Resources Board (CARB) and is considered legal for street use. Visit this link for more information regarding Frequently Asked Questions About Emission Laws And Regulations.
This unit is very easy to install and is supplied with fully detailed installation instructions. (Allow approximately ½ hour for installation) Use of the K&N Filter Charger Kit is an inexpensive way to clean, protect and prolong the life of your air filter.
This intake is compatible with Miatas equipped with anti-lock braking system (ABS). (The location of the ABS module required Mazda to relocate the windshield wiper fluid reservoir to the area behind the stock air intake box.)
