Are K&N air filters worth the expense on cars?
eg I can buy a new K&N for $100 and normal one for $40. But the K&N will need $20kit to clean (multiple times)
Makes sense.. keen on hearing others views

Project farm does exhaustive reviews of all sorts of things. He's just done one on air filters today, including the K&N. The take-away from this was:
"Yes, the K&N has slightly larger airflow, but lets all sorts of stuff through. Not recommended if you care about your engine."
