Running a factory air box on your 2013-2014 Focus ST is sort of like a marathon runner trying to breathe through a paper bag; not the best idea with performance in mind. Now is the time to replace the stock air box and upgrade to a cold air dam intake system from Airaid!

Airaid's cold air dam intake retains the stock air box location, but gives the intake system a huge boost with the addition of a massive air inlet. This new inlet provides a free-flowing supply of constant cold air. The cold air dam heat shield mounts in the factory air box location and utilizes the factory cold air inlet ducts while adding additional cold air passages to the filter. Weatherstripping seals the heat shield to the underside of the hood to keep the filter isolated from the hot engine compartment air. A high-flow SynthaMax air filter replaces the stock filter to greatly increase the amount of air entering the engine.

The SynthaMax filter is a non-oiled filter made up of an inner and outer layer. An outer layer of wire mesh provides durable support of filtration which helps prevent the air filter from collapsing under high air flow. The inner layer consists of two layers of synthetic materials that both provide outstanding air flow and high filtration. Particulates are first trapped in the outer layer of synthetic needle-felt polyester material which is designed for wet and dry filtration with high air flow capacity. The inner layer is a backup that captures any remaining particulates. Airaid SynthaMax filters are made completely of synthetic fibers which are washable and do not need to be oiled making clean up easier.

Cold air is denser than hot air which means that an engine breathing colder air is going to make more power than the identical engine breathing hot air. Airaid is driven to create systems that flow the coldest air and make the most power. Every system is designed specifically for each vehicle application and offers a trouble-free installation using simple hand tools. All necessary installation hardware is included as well as easy-to-understand instructions written with the do-it-yourselfer in mind. Airaid systems are made in the USA!

*Will also fit the 2013 and 2014 non-turbo 2.0L Ford Focus.
