1990–1997 Mazda MX-5 Miata Intake & Intercooler FAQ's

Please read our FAQs page to find out more.

Do intakes add power on an NA Miata?

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

Where does an intercooler fit on an NA?

Stock NAs are naturally aspirated—intercoolers apply to turbo/supercharger kits. A front‑mount intercooler with efficient end tanks keeps IATs stable under boost.

Are larger throttle bodies or manifolds worth it?

On higher‑flow NA or FI builds, a larger throttle body/manifold can help top‑end. Gains depend on cams, header, and calibration—plan parts as a package.
