If you don't mind me asking Simmo, how much for the K&N and from where?
Is it a specific WZ ST filter, or does it fit the whole WS-WZ/WZ range?
After looking on eBay I found a filter to suit 2013 Fiestas under the part number:
K&N 33-2955 Air Filter
I'd love some more TSSS! ANd I've always had good results in general with K&N filters.
