I have an HKS intake but the filter is gong bad, all dry and brittle. I was going to get a replacement filter, but HKS offers two kinds the 2 layer wet ones and the 3 layer dry ones...now which one is worth getting and better(performance wise)??

 

2 layer wet is better for 'performance' but 3 layer dry one can filter more. if you live in dusty area, dry one might be better.

 

which one i better 200mm or 150mm??

 

i believe hks intake for evo is 200mm.

 

thanx i ordered a 200mm one hopefully its the right one!!
