Miata MX-5 ND 2.0L 4-1 Header

The JDL Miata MX-5 ND 2.0L 4-1 Header is engineered to significantly boost the top-end horsepower and torque of your 4th Generation ND MX-5 Miata, while also maintaining solid mid-range power. This 4-1 equal length header is designed for the ND1 and ND2 chassis, offering maximized power potential for both naturally aspirated and supercharged applications. It utilizes convergent merge collectors to promote high velocity flow, and all flanges are surfaced true to ensure proper gasket sealing. The port matching is done for optimal flow, and the entire unit is handcrafted and precision TIG welded with back purging for maximum strength and durability. Installation is aided by included gasket and hardware for the header outlet, along with an O2 sensor wiring extension for correct placement. For those seeking to further enhance performance and reduce under-hood temperatures, a thermal ceramic coating is available as an optional upgrade. This coating helps to reduce radiant heat, lower engine bay temperatures, protect surrounding components, and add an extra layer of corrosion protection. Installation Pro Tip: It is recommended to have an OEM manifold gasket on hand to ensure a proper seal. Disconnecting the passenger side engine mount and lifting that side of the engine can make the installation process significantly easier.
