Works as advertised. Not as much horsepower, but slightly faster throttle response. Thanks to Mazda for not restricting the air intake on Miatas. What I really wanted, however, was to be able to HEAR the engine so I could shift faster without blushing or looking at the tachometer. It helped a bit but the kit on my 4 wheel motor sounds like a beast compared to this smaller motor. Maybe it's because it's only 4 cylinders. Therefore 4 stars for the easy installation.
