yes..agree with cannon fodder. Although I supporter of HKS, for air-filter, I just stopped using them long time ago.
SARD is top of the chart in one of the Option Fans magazine test out of comparisons between all air filter if I remember correctly. HKS is the last, sad to say. If u want open pod, go for SARD, K&N or Airinx (Greddy) but not Pipercross. Piper cross material not suitable for high temp under the bonnet like evo !
Blitz material is not good for evos and K&N, I was told is too small for evos engine la. Those open pod type.
The best is suction kit or filter box. Get cold air intake mah..Monster, ARC. In fact K&N or Ralliart replacement kit on ori air intake box should be one of the best setup. Of course some says open pod feels better coz with open pod, u can hear the turbo spool and air suction OUT LOUD !! so feels better lor.
my dua sen sahaja.
