I do not know what colour standard ARC filters are but these have ARC embosed on them on the inside. They are arnt that dirty, must be the pic. Where could I get some new filters from when they need replacing?

Thanks

 

I'd say vividracing.com but I'm sure there are shops in the uk that sells arc. Did you buy it new? I have the same intake. It is a nice piece. Btw car is looking good.

 

a-ok!
