The AIRAID 863-408 direct fit replacement air filter for the 2013-2014 Ford Focus ST & 2013-2014 Ford Focus 2.0L.
Believe it or not, the 2013-2014 Ford Focus was the best-selling car on planet earth. Thanks to increased demand from China, Ford sold over 1 million copies in 2013. That's 2 cars sold every minute, which is a lot. Many engines were available, but two of the most popular was the gas-powered 2.0L 4-cylinder. The 2013-2014 Ford Focus S, 2013-2014 Ford Focus SE, and 2013-2014 Ford Focus Titanium could be had with a 160-hp 2.0L that came with such novel features as direct injection and Twin-Independent Variable Camshaft Timing (Ti-VCT). The hot 2013-2014 Ford Focus ST came with a much more potent 2.0L EcoBoost, which sported a special low-inertia turbo that could deliver a stout 252-hp and 270 lb-ft of torque. Both versions of the Ford 2.0L offer excellent performance for their respective models. But if you simply install an AIRAID 863-408 direct fit replacement air filter, you could get a lot more power from your modern Model T.
When an engine ignites gasoline inside the cylinders, oxygen has to be present in order for it to burn. The air is piped in through the intake system, which delivers outside air directly to the manifold. In order to ensure that no contaminants get inside the cylinders, the air must first pass through a thick paper OE air filter that's located inside the air box. These are called 'surface loading' filters, because any dirt they remove, stays on the surface of the filter. Over time, this buildup will start to reduce the airflow and cut power. That thick paper filter media also limits the volume of air that can flow through it, even when it's clean. So your little Ford may have never been able to live up to its true performance potential.
To reduce airflow restrictions and improve performance, the AIRAID 863-408 direct fit replacement air filter uses special synthetic filter media called SynthaMax. This proprietary material consists of two layers, which are designed to stop dirt particles. The first layer of needlefelt polyester captures larger dirt particles deep inside its web of synthetic fibers. The second layer of chemical bonded rayon and polyester is engineered to stop any smaller contaminants that make it past the first layer. This dual-layer protection ensures that your engine is getting the cleanest air possible. It's also a 'depth loading' filter, which means the dirt is stored inside the material, allowing for unrestricted airflow even as the filter gets dirty. Then every 30,000-50,000 miles (depending on road conditions), you simply remove the filter from the air box and clean it using the AIRAID 790-558 filter tune-up kit.
Since the AIRAID 863-408 direct fit replacement air filter fits in place of the OE air filter, no under-hood modifications are required. It won't void your factory warranty either, and it comes with a No-Hassle Lifetime Warranty. So if you're ready for a reusable air filter that will actually improve the performance of your Ford Focus, this AIRAID SynthaMax performance air filter is for you.
