Air Cleaner Trim. Fits Evolution 1340 and Twin Cam-equipped models with stock air cleaner (except '08-later Dyna, FXS, FLS and FLSTSB). The sinister Harley-Davidson #1 Skull logo dresses for a night on the town. This complete die-cast aluminum collection has been polished and chrome-plated to a brilliant shine, then finished with a contrasting black-filled Dark Custom Skull logo. The black-filled race track stripe and recessed hardware pockets provide added depth and dimension. Includes chrome-plated mounting hardware.
