Sound enhancer removal cap made by Leg Sport of Japan for the 2016+ ND MX-5 Miata. This cap is designed for those who wish to bypass the intake resonator and change their induction sound.

Leg Sport claims with this cap that by bypassing using their cap, it will smooth out the induction noise and also provide a mild increase in throttle response.
