The Focus cup partnered with K&N and followed their recommendations to use their E-9289 filter. The K&N E-9289 Air Filter is designed to increase horsepower and protect the engine by reducing restriction and providing excellent filtration. The E-9289 custom air filter is manufactured to replace the air filter in the 57S-4000 performance air box and it comes with a K&N embossed lid cap. The filter media can be washed and reused repeatedly.
