Unlock Power in Your Mazda MX-5 ND

Transform the throttle response and power delivery of your 2016+ Mazda MX-5 Miata ND with the Grams Performance 70mm Drive-By-Wire Throttle Body. The factory throttle body is often a bottleneck in the intake system, especially on tuned or modified engines. By increasing the bore size to 70mm, this unit allows for a higher volume of air to enter the combustion chamber, resulting in improved acceleration and a more aggressive power band.

Why Choose Grams Performance?

  • Increased Bore Size: 70mm ID for maximum intake efficiency.
  • Direct OEM Replacement: Designed for a perfect fit without the need for adapters.
  • Plug-and-Play Connectivity: Retains full compatibility with factory electronics.
  • Enhanced Drivability: Sharper throttle response in all driving conditions.

Engineered for the enthusiast, this throttle body is built to handle the rigors of spirited driving and track use. The high-quality construction ensures that you receive a product that is not only powerful but also incredibly reliable. Because it is a true plug-and-play component, installation is straightforward, allowing you to spend less time in the garage and more time on the road. Whether you are looking to squeeze every bit of power out of your Skyactiv engine or you simply want a more responsive pedal feel, this Grams Performance upgrade is the ideal choice for your Miata. Find this and other performance parts at GGCRACING.
