Tuning Parts for Ford Focus RS MK3 15-19

K&N 57 Series FIPK Air Intake Kits represent a dramatic performance improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded intake tubes that can reduce air temperature and decrease sound over a metal tube. Air flow restriction can exist between the air filter and engine reducing the benefits of a K&N performance air filter. K&N air intake kits virtually eliminate restriction in the air path by replacing the filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which in turn adds power.

AEM has reinvented the Lifetime performance aftermarket air filter. Our DryFlow Synthetic filter is the first performance air filter that does not require filter oil to filter and trap dirt and contaminants, and delivers industry leading filtration and durability that is unmatched by our competitors.
