I will be running a t25 turbo setup and i need a small filter. I like the hks but they go for about 100 on ebay. do you think that the hks will flow significantly better than the $20 generic hks filter? foam is foam right? also if anyone knows anything about the flow rates.....i know you get what you pay for but i wanted to ask around before i blew 100+ on a name brand filter. thanks
