I have used K&N air filters on my last four cars. I have always experienced the same performance boost after installing one. My gas mileage goes up between 1 and 2 miles per gallon, and I have tested and verified about a 3%+ increase in horsepower. One note to consider. Even though the filters are life-long permanent filters, they do require at least annual inspection and servicing, more frequent if you live in a dusty climate.
