got it from an ebay buyer in edinburgh and Derek helped me shipping it over at minimal cost!
£220 + £10 shipping, was the best price I could find it at, and I phoned ALL K&N stockists in the NW !
easy to fit, I'd say yeah, only tricky bit was the MAF sensor you need special bits (called security bits) to take it off. Also, the fact that you can add the suction cone or not gives you a choice. I just put it on for the summer, but think I'm gonna keep it as the design makes it basically impossible for water ingress.
If the price is right for the Cosworth setup (plenum + intake) I might sell mine! It's blue though
