Anyone had any problems with these. Myn has developed a loud whining noise but if i recall it only seems to be when its hot? (I could be wrong on that) I have spoken to my tech on the phone (Chris Mason v.helpfull) he suggusted that there maybe a blockage due as its very Juddery at high revs like its not getting enough fuel? Im going to change the filters when they arrive on wed but between now and then any advice would much most greatful.

cheers guys.
