VXR8 OTR Air filter

[MilkyV6]

I've been thinking for a while that I'd spend some money on an otr filter. I've looked at importing but with tax it works out to be same price as Walkinshaw's unit (coincidence?) So it seems it's a choice between walkinshaw or monkfish. Now the walkinshaw is £540 but MF is over £600 (with in fill panels) so my question is is there any difference between the units apart from the obvious £70???

Yeah that was my original question on here why is MF circa £60 more expensive than walkinshaw?
