RZCrew Airstream Intake Manifold for Mazda MX-5 NA NB 1.6

This is the Airstream Intake Manifold for the Mazda MX-5 NA and NB. This newly re-designed intake manifold for the B6 NA Engine features

  • A new flange system for easy bolt-on installation
  • A newly designed plenum with optimised airflow for better performance.
  • Longer runners and reworked trumpets for better NA and Turbo performance along the whole power range even on Automatic cars

All Rzcrew Racing Airstream Intake Manifolds feature high capacity plenums for better engine response and calculated oversized runners to ensure a faster airflow into the engine head. The flange is made to match the stock head for seamless and turbulence-free airflow in the combustion chamber.

Both the manifold and throttle body flanges are CNC machined from billet aluminium, with the remainder of the manifold being hand welded to produce an incredibly high quality and lightweight product.

RZCrew’s proprietary AirStream technology features internal trumpets angled to optimise airflow and ensure each cylinder is fed with the same amount of air, this results in improved power through the entire rev range.

RZCrew’s Aluminum intake manifolds are direct-fit replacements for the original intakes and designed to work with stock or oversized throttle bodies. Please check the specifications for the supported throttle body diameter, plenum size, etc.
Our manifolds are designed to be heavy-duty to handle racing application without showing weaknesses or cracks.

We highly recommend having your intake manifolds professionally installed and tuned with a standalone to get the best performance out of our intakes.
