DNA High Performance Air Filter Service Kit Generation 2 Compatible With Motorsport DSK-3001 PN: DSK-3001Auto

The percentage of dust that the filter retains during a laboratory test, following the ISO 5011 protocol. In cases the air flow of the DNA Filter is extremely high we include with the filter special instructions. DNA filters have a filtering efficiency of minimum 98% (ISO 5011 test). Good quality OEM paper filters are from 97% to 99% and the foam filters are from 92% to 97%. Filtering efficiency is the amount of "dirt" the filter can maintain (stop) and protect the engine efficiently. For example, the DNA Filter for every 100 grams of dirt that it will receive, it will "trap" 98-99 grams, and this applies even to fine dirt as small as 5 microns.
