K&N does a great job! Bought this filter for my 2005 RX-8. No problems at all. Have a K&N filter for my other car as well. You may pay a little more initially, but being able to clean and reuse these filters makes it worth it. As to any feeling of an increase in horsepower, not so much, I guess you could say it pulls a bit better once you get to the higher rpms, gotta love a rotary...9k redline!...more info
