30mm Velocity Stacks for Mx-5 Miata NA NB ITB Kit

Product information

PRE-ORDER!! This kit is ready for shipment after week 2 of januari

Get the most out of your individual throttle body setup with our 30mm Velocity Stacs Spacers. These stacks allow you to customize your intake length to suit your performance needs and engine configuration, giving you the ideal runner lenght for setup.

CNC machined, precision fit with our range of ITB Kits, comes with required hardware and gaskets for installation.

Intake runner length significantly impacts engine performance, with longer runners enhancing low-end torque and drivability, while shorter runners boost high-RPM horsepower. The optimal runner length depends on the engine's powerband needs, very high revving ITB engines may benefit from the shorter 30mm stacks such as these.

Standard Mx-5 engines seem to benefit from longer stacks, optimal is a 130mm combination with our kit. This doesn't always fit with ABS or RHD unfortunately, hence we choose for 80mm as default. For those looking for 130mm velocitystacks, we advise to take a look at our 50mm Velocity Stack Spacers for ITB Kit

Combinations with these spacers, 30mm stacks and a filter baseplate can be made aswell, for example with our Pipercross PX600 Velocity Stack Package for Hummelink ITB kit NA NB or a self-composed combinationBefore purchase, please check your engine bay clearance to ensure proper fitment!
