question about injen intercooler pipe kit....
why do you want to change it? the k&n filter that comes with the injen kit is better than the hks filter. the hks filter is a dry foam filter, which is good becuase its dry, but doesnt filter as much as the k&n. the only problem with the k&n is that if its over oiled the oil can get on your maf sensor, so youll have to clean it with a maf cleaner.
