The pre-filter I ordered was from the link on page 1 of this post.. the 450r one. It did NOT fit the 700xx filter, so I customized it to fit on the outside of the lid to stop debree from coming in.

It cost me 12.00$ to make my own custom Outerwear lid. You can buy sheets of the water proof Outerwear for 10.00$.

I use the stock air filter and have an EHS lid I clean mine with soap and water and then oil it with silkolene aerosol oil. Its really tacky and so far does a good job.
