Manufacturer Info
GREEN sports air filters stands for quality since 1991. All air filters are therefore made from 4 layers of cotton. The rubber connection flange is vulcanized in a special way and does not tear. A big advantage of GREEN compared to other suppliers is that the filter is not too richly supplied with oil. This means that no problems can arise with the air mass meter. The filter keeps the sporty green color and does not turn brown.
In the GREEN factory, all sports air filters are developed by the engineers who work at GREEN in the R & D department, using the most prominent equipment. Then the car is equipped with the developed air filter and tested on a power bank. Only when the result meets the requirements set by GREEN, for example in the capital gains, is the product included in the program.
All air filters are precisely matched to the individual cars to achieve the best result. GREEN is not only about the look or the sporty sound, capital gains always have priority.
