Hahaha I need glasses! :stupid:PIMPIM, I'm afraid u asked the wrong guy... I didn't mentioned anything about HKS, I think u are refering to JAHAX.
Anyway, since u asked, I think its because sponge type filters tends to harden and breaks into ashes and therefore being sucked into the engine, correct me if i'm wrong Jahax....
Yup, I believe K&N will be great since its so dirty everytime, that means it could actually filter out a lot of dust and particles....i think K&N is ok..
i was told the same thing BNR. i myself used to be a big fan of HKS mushroom filter, suction is amazing but it tends to brittle when it ages.PIMPIM, I'm afraid u asked the wrong guy... I didn't mentioned anything about HKS, I think u are refering to JAHAX.
