I just installed this filter & have not noticed any performance differences.I used one of these before for about 6 years in this car. After this installation, I researched & found that there are questions about how well these units actually filter. Even K&N seems a bit murky about filtering efficiency. In one good experiment/analysis, the K&N clearly let through more dirt than a Mazda factory air filter and one premium racing filter, but less than 3 others,so I'm not so sure now a K&N is for me.
