Do K&N filters improve performance?

These filters are designed to boost horsepower and torque. That is because allowing more air into the engine tells the ECU to inject more fuel. This gives you a more complete and potent fuel burn. Test results have proven that these oiled cotton filters provide up to 50% more air.

Do K&N Filters damage engines?

K&N filters will not damage the engine internals but they can damage or at least coat the Mass Air Flow sensor if your car has one and most cars now do. The oil that the K&N filter is soaked in can separate and contaminate the wires of the MAF.
