I think I may have accidentally discovered where the item is moot, regardless of compliance.

Look again at that photo of the stock 1.8L Miata. Note that there's a plastic cover over the area on top of the nose, in front of the radiator. This Jackson Racing part pulls air from that area when that cover is removed, and I cannot think of any way where removing that panel is compliant to the regs. Therefore, even if that intake is compliant, I don't think it's nearly as effective unless another non-compliant mod is also done, negating the whole point.

The 1.6L Miata seems to be open there, so may be useful for that car.

Agree/disagree?
