I have a 1995 Mazda protege with the 1.5L engine. I have had the same dirty air filter since last August 2008, and was noticing that my Mazda's performance was failing over time. I did a tune up last week and decided to change that dingy paper filter. I bought the K&N filter for 35 dollars, which is great, because two disposables would cost at least 30 dollars. All I can say is AMAZING!! I feel the response, and no more hesitant acceleration. My mileage is noticeably better as well although I haven't had time to calculate the numbers yet. I thought it was my tranny before, but it was a lack of good filtering and airflow. I would highly recommend this product to tuners, and drivers looking for that extra couple MPG.
If I buy another car, its K&N all the way.

I drive a 2000 Mazda Protege SE with 1.8litre engine. At 30,000km I installed a K&N Filtercharger. The car immediately had more power, I thought wow this is great! After a couple of fill ups I checked the fuel consumption and noted a little less than 15% improvement in km per litre. Why isn't K&N standard equipment on new cars?

I got this performance air intake for my 02 Mazda Protege 5 and I love it. It took about an hour to install but I also had to relocate my coolant housing in the process which was also easy. Since it was installed it has provided a noticeable increase in power to my car, now that the constricting factory air system is gone. I would advise that you use caution during rain or inclement weather of the sort as the location of the filter on your car might allow water to go into the engine, which is bad, otherwise I would highly recommend this product to anyone looking for an increase in airflow and a little added power to their car.
