On my focus I run a K&N 57i with auto specialists headshield, ST170 snorkel with some hoses I adapted to aim directly at the filter and 2.0 auto air deflector





You cant quite see the cold air feed but it is DIRECTLY under the filter aiming straight at it. Mine I would say does suffer from heatsoak so I am thinking of enclosing it better and adding a second cold air feed from the bottom grille past th battery tray and round the other side
