I use it in my 06 Nissan 350z. Overall the Spectre filter is good. I can tell there is little improve on the gas mileage, however I can't feel any hp gain. Anyway, I don't expect to gain hp by using the filter. There is a minor fitment issue that the Spectre filter is slightly thicker than the stock filter. It made a bit difficult to close the cover after installed the new filter.
