cjac Posted February 26, 2008 Share Posted February 26, 2008 Hi all, I typically forget to do these things and thought of it today. I picked a couple new ones and pulled out the old one.....it was bad! Amazing difference compared to the new one, both in shape, as they tend to concave with air flow, and in color/dirt! If this triggers a few of you to do the same, well then I can say I did my good deed for the day......Regards, Chris Link to comment Share on other sites More sharing options...
