I\'ve just found that Halfords have their own brand cotton gauze filters now, so figured I\'d see if they fit. And they do! So I now have a nice pair of shiny red cotton gauze filters for less than you\'d pay for a k&n!
What do people think? It\'s a bit of a tight fit, but I got them both in there! I have eventual plans to make a alluminium heat shield to try and keep some heat away from them, but it\'s a start.
