I dont have engine damage but my filter still lets dust into the intake tube. and i have done alot to stop it. if you can think of a way for me to help let me know. Also i can see that most people on this forum that are having trouble just want to bitch about it. our dont read the forum much anymore. I cant beleave you people bitched so much about this and now a member is swinging a big bat and you cant back him up. you people better step up or all of you can kiss my a$$
