ITB's are a must have when building a naturally aspirated machine. The stock intake manifold gets replaced for a set of individual throttlebodies or ITBs, giving each cylinder their own throttlebody, resulting in the best flow possible. Moving the throttle this close to the head results in instant throttle reponse. ITB's are knows for amazing intake sound, this kit is no exception!
 
This kit is designed to be as plug and play as possible, and focussed on maximum naturally aspirated power gains, aswell as reliability and quality.
After loads of flow calculations and confirming dyno test with various diameters/lenghts we've designed the optimal Miata ITB kit. The runners on these ITB's are specifically made for the BP engines, resulting in optimal 'all motor' performance.
 
The kit features:
- Fully billet adapter manifold, velocity stacks and throttle cable wheel.
- Cast aluminum throttlebodies, precision machined bore/butterfly valves
- Vertical throttlesbodies, allowing for much more enginebay clearance.
- Lasercut stainless steel fuel rail bracket. Our 1.6 kit uses a fuelrail bracket which works with the OEM fuelrail. The 1.8 kit doesn't require any bracket.
- Original TPS location, and plug and play fit with the NA6 TPS connector.
The NB kit includes a adapter harness. Allowing for a plug and play conversion without cutting wiring.
- The kit comes with 80mm stacks. The 80mm stacks will fit any ABS and RHD model.
- Fully adjustable butterflies and idle screws for optimal throttlebody synchronizing.
- Mechanical synchronized out of the box.
- 1/8npt vacuum ports
