There are plenty of people over the years that have fabricated or adapted air cleaners to IR injection stacks whether they be individual filters for each tube or filters for each bank of 4 or 1 big one that covered the tops of all 8,but I agree with superstocker it is a full race setup and filters will cause restriction and require recalibration to account for it and that is easier said than done. Unless you follow the current trend and convert the the old school system to EFI,which from what I've heard makes it a much more streetable setup.
