"D1 Spec" Panel Filters, Reviews?

[griffo]

Hey guys, while browsing the ol' bay of E last night at service items for my K11 I came across these...

They appear to be a cheap performance panel filter. Being cheaper and from the likes of Hong Kong etc. always leave me skeptical about there quality mind (although usually items do tend to be just as good) I was just wondering if these filters had been heard of on here and if anybody had any views on them??

Possibly an ideal cheaper alternative to the likes of K&N/Pipercross etc.?

Seen catch tanks made by D1 Spec, quite nice as well but this filter is something new for me
Looks very nice, wonder if its any good.

Are they washable like the K&N? IF it is, i think is worth while . Wash and reoil a few times, then you got your money back .

Shame i just got some air filter!!!
