HKS EVC inline vacuum filters

[AgtX]

Im looking for replacement HKS EVC inline vacuum filters 4mm & 6mm, the cheapest..& only ones I could find so far are £30 total, seems a bit of a ripoff, anyone know where to get them cheaper?

Thanks.

Sumopower do them for about £11 if i remeber rightly. Are they really needed though?

yeah that's where I saw them, after shipping etc, its £30. The manual says they need inspecting after 3000 miles, they stop any oil getting into the unit, keep it accurate I guess. One of the filters fell apart a while ago & it boosted freely over 1bar, glued it back together probably better to get new though.
