These DNA power filters are at least as good as the K&N filters! Tests show time after time that the DNA filters increase the power and filtering. These DNA filters have a very long warranty and are made of cotton, so you can maintain them perfectly! In addition, these filters are much easier to tune than cheap paper filters.
