That's what I had on mine when I first removed the air box. They are foam with an internal spring. It come with Tuneboy, yes, they are the unifilters. Mine were red so it went faster haha. I already had the Staintune exhaust with crossover, had a dyno done before air box removal and was 126hp. Put on the unifilters and went up to 137hp, then 142hp with the tune. Changed to k&n 2780 later and now Ramair. All fit under bear claw but I did cut mine.
