Brian's Application Notes: Our dyno work with and without any filter in the factory airbox found no gains on ND1 Generation Miata. And our dyno work with several brands of intakes on ND1 generation found zero power gains with any of the complete intake choices. ND2 generation Miata has quite a bit better breathing at the top end, so we cannot say at this time that there are no gains with ND2. Nonetheless, at this time our opinion is that these choices are likely giving you only a washable filter, not a performance gain. We will seek to repeat some of our tests on our 2019 as time permits.
Replaced my factory filter with this. No performance gain but nice to know it'll last and is easily cleaned.
