Hey guys,
Was doing some searching online for a stalling issue that I'm now thinking is the IAC and found this thread. I know performance is something we are interested in and prompts the
K&N filter. Are you suggesting going back to restrictive paper filters again? I had a K&N and then switched the the Amsoil 2-Stage Foam Filter, but it was also an oiled filter. I am an Amsoil Direct Dealer and one of the things we were told to emphasis when we sold these filters is not to over oil these filters. Fords were very sensitive to oil getting sucked in. Last fall Amsoil released their new line of Ea Air and Oil Filters. These Air Filters are dry filters using nano-fibers that were originally developed for the M1 Tanks that encountered fine dust in the mid-east after the first Gulf War. These filters are also reusable but they are dry, so no reoiling. They flow as well as the wet gauze style filters but filter 50x the dust that they do. Cleaning involves just a shop vac every 25K. This could be an option for those concerned about loosing air flow by going back to a paper filter.
If you are using the stock airbox, the part number is EaA191. They are working on aftermarket models that we can use with non-stock intakes. I just bought the stock model and replaced my 2-Stage the other day. When the aftermarket model is out, I suppose I'll have to make the sacrifice and finally get that pipe.
