Improves Horsepower. Now you can improve the acceleration and performance of your Fiesta ST with a K&N Drop-in Replacement Air Filter. Simply replace your stock restrictive paper element with a new, high flow cotton gauze K&N filter. Feel the increase in horsepower and acceleration instantly, all while providing exceptional filtration for your 2014+ Fiesta ST.

Filters out Harmful Contaminants. This oiled Drop-in Replacement by K&N will filter out harmful contaminants with its unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze, sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers, which causes a tackiness throughout the cotton's microscopic strands. This results in a powerful filtering media that ensures superb engine protection.

Reusable Filter. Designed to be cleaned and reused, this red K&N Air Filter will last up to 50,000 miles before needing a cleaning, dependent upon driving conditions. This filter won't void your vehicle warranty and is backed by K&N's Million Mile Limited Warranty.

Application. The K&N Replacement Air Filter is designed to be a direct drop-in replacement for the stock air box on all 2014+ Fiesta ST.
