Can't help with your lid issue, but will say this if you have lots of dust in your area.....Not sure what air filters the grizzlies use, but I am a firm believer in paper element filters.....the oil soaked cloth type filters do not trap enough particulates for my liking, move more air YES, but at the expense of proper filtration. I have had some very large pieces of debris make it through those K&N type filters, and ever since then will only run paper filters. I just look at what commercial trucks run....paper filters...:wink2: ....steps down from soap box. :grin2:
