Fits 1999-2005 Mazda Miata with stock air box

The Green High Performance Air filters are undoubtedly the best drop in oem replacement filter on the market. They are not sold in big box auto parts stores as they do not want to be labeled as "K&N filters" by people not in the know.

We use Green Air filters on our racecars rather than the K&N filters that are assumed to be the best in the world. This is going to be the best drop in air filter for your 1994-1997 1.8 Spec Miata racecar. The Green Air filter flows better when compared side by side with the K&N and have less filter element to restrict air flow. When you hold a Green filter up to the light and look through it you can see more light coming through than if you were to hold up a K&N filter, which means it has less restriction. We have used these filters for years and love the quality and performance, you will too!
