Review on Spectre Performance 9731DK Air Filter Wrap - Enhances Engine Performance, 1 Pack by Ben Robinson

I just found out about these "temporary" cases and I don't understand why I've never bought them before. I clean and oil my aFe CAI permanent filter every 6 months. But if this case can filter out all those huge chunks of dirt, bugs and debris it will greatly help my filter last a lot longer. Some claim that this filter can help keep water out of the air intake. No it's not, but I don't get in 4ft of water often. (Buy the right hose!) But as a pre-filter to protect my oily filter, it's perfect. This cover is about 1/4 the price of the "Signature" version!
