Well there is definitely no room for a filter on my F-1A setup since I'm using the House of Boost Renegade bracket setup. I have about 1.75" of clearance between the blower and radiator core support so my only choice is to run a screen for at least some protection. The only company I can find is Turbo-Guard but they say their screens need a 1" lip to grab onto. The F-1As only have about 3/4". Any other ideas besides making my own from Home Depot mesh screen?
