Well I did say: My K&N is getting dirty rather quickly strangely enough (visual appearance anyways, but any excuse will do), so I may look into ordering an 'S&B' air filter from the States as mentioned previously and then experimenting with removing the reducer. Only thing is, as with anything I do, I'll have to take it back to the 1/4 to make sure I haven't lost any power. It's certainly cheaper than a dyno, but still... for $40 each time I go, I'm kinda over going. What I have now feels to me like it works so I am becoming less inclined to change it. Well I'll put an S&B on, but I don't know about the reducer just yet. sorry Daryl I missed that info. lack of sleep.
