what kind of shipping time and cost is there ? have any testimonials from anybody stateside ??
Shipping costs would be about 20-24 Eur, average time about 10-14 calendar days, depends of how much days parcel will bog in NY custom depot.

For impresions could ask to willmelee4food; mech120. Some guys outside of the SMJ in north America ride with my carbs.

If you are interested for the last one then it is shipped to UK. If you are interested in available the same like the first one in thread if need catch can available as well.
