1999–2005 Mazda MX-5 Miata Intake & Intercooler FAQ's

Please read our FAQs page to find out more.

Do intakes add power on an NB?

A cold‑air or high‑flow intake sharpens response and sound; gains grow when paired with header/exhaust and proper timing or tuning.

Where does an intercooler fit on an NB?

Stock NBs are NA—intercoolers apply to turbo kits and Mazdaspeed models. A front‑mount with efficient end tanks keeps IATs stable under boost.

Are larger throttle bodies/manifolds worth it?

On higher‑flow NA or FI builds, a larger throttle body and matched manifold can improve top‑end. Benefits depend on cams/header and calibration.
