Considering the foam filter controversy with silicon in the oil (not making that an I agree) so anyone used the above

$43 USD

A few of the EVO guys have been using these & all have nothing bad to report

From what I understand, it is exactly the same as the HKS unit... Right down to the pricing. One of my mates who's got a Ralliart Lancer was tossing up between the 2 & landed up going for the HKS unit (Via PhatGT) as it was proven not only with the EVO crowd, but also with the Subaru crowd

So in my mind, just stick to HKS Well proven among Lib drivers across the land
