About inlet , i am actualy on half way to build one :/ , got the straight pipe , just need the 90 degraa and 45degree silikon house , i also got the oil cach tank from tham , just wana change the silicon tube that i recive with it so i will order that and the vacum tubing from tham also . And a litle air filter for the tank becouse i will not bring the flow back to the inlet . . . But it would be good to know the price . U can ask them please if its not a problem to you . Also i gess it would be less expensive than building all of those things separately ^^ ? Is the efficience better or just the look also with that o_O mby better and smoother air flow ? Dont know
