NOPRO | Big Bore Throttle Body for Mazda Miata MX5 NC

High-precision machining has been applied to the inside of the funnel, increasing the area at the time of opening by 7% compared to the stock, and by making the butterfly larger to match this, the amount of air intake and flow rate are increased. After replacement, more air can be sent to the engine with less throttle opening, improving throttle response and torque feeling at low to medium speeds.
★ Stock bore diameter Φ60, machined bore diameter Φ62 (funnel-shaped entrance Φ67)

This part has a noticeable effect even in its stock state, but for cars that have already had their intake and exhaust systems tuned, such as the camshaft, exhaust manifold, and muffler, the increased intake efficiency will further bring out the engine's potential across the entire range.

This product is recommended for those who want to easily improve engine response, or for customers who have already had their intake and exhaust tuned and want to further improve their performance.

Can be installed on early model, AT, MT (5/6 speed) NC.

This is especially recommended for vehicles that have traveled over 100,000 to 200,000 km, as the drive motor, sensors, etc. will deteriorate.
