AMS 2016+ Focus RS High Flow Air FilterIntroducing the AMS Focus RS High Flow Air Filter

The new AMS Ford Focus RS High-Flow Air Filter is exactly what your hot hatch needs to breathe deep and produce big power! Simply dropping this filter into your car’s stock air box alone picks up 10whp at 5500 RPM! This is the first in a long line of performance parts you can expect from AMS Performance for the RS. The engineering behind our filters is what sets them apart from the big name brand competition.

No Messy Cleaning Process

Our AMS Filters are made with materials specifically designed for automotive applications, a synthetic non-woven multi-layer structure. The filter does NOT use oil or chemicals of any kind to aid filtration and will not degrade over time with exposure to varying temperatures and humidity like similar cotton based filters. As well as the lack of fillers such as oil, that can be pulled from the filter creating a less efficient media, it creates consistent performance between all cleanings over the lifetime of the filter. The filter is easily cleaned by blowing compressed air across the media from the inside out to blow off residual dirt and dust.

Built To The Highest Standard

To take it one step further the filtration media is tested using the ISO 5011 Fine Testing Standard to a minimum of 97% efficiency rating.

One Filter To Buy

This filter will be incorporated into our Carbon Fiber Cold-Air Intake System so you will NOT have to buy another filter down the road.
