You may be better off staying with the genuine Mazda part. I purchased a generic brand for about $17, installed it, and then noticed an increase in noise from the engine, especially with hard acceleration and climbing. I may have also noticed a decrease in gas mileage. Although both filters looked nearly identical, my guess is that the generic version did not seal properly. The white filtering material looked identical, but perhaps there were some differences that contributed to the problem.
The Mazda version is only $19.95, so not enough of a difference to justify an aftermarket part.
