K&N all the way here too on all my race cars, Corvettes and Motorcycles.

Consiracy Theories that you have mounds of dirt in your motor from these filters are rubbish.

All and any tiny pieces of "dust" that makes it into the cylinder chamber is incenerated upon detonation OR if not it is passed out of the motor through the exhaust port on the cylinder head into the exhaust and then burned up again at the cyatilic converter.

Also if for some other reason it is left behind it is caught by the oil and then filtered out by the oil filter..
