What is everyone's opinion on replacement air filters? I put a K&N filter in the last time and it is a bit dirty now. So the question is, should I do the clean and oil routine on it, just buy another one, or go for an OEM type filter?

Thanks!

 

You will get lots of opinions on this one. I say keep the filter changed and you will be just fine. No reason to go with reason to go with performance stuff, except that it makes you feel like you did something cool to your car. You've spent the money on the K&N, so just do the recommended cleaning and oiling. Don't get crazy with the oil, however. You could damage the airflow meter.
