These intakes use only
non-metallic rotationally molded tubes that can reduce intake air
temperature and decrease intake sound over a metal tube. Restriction
can exist BETWEEN an air filter and the engine reducing the benefit
of a K&N Air Filter. The weakest link in the airflow "chain"
robs a vehicle of its natural horsepower. Often that weak point
is the factory air path leading to the engine.
K&N air intake kits
virtually eliminate air path restriction by replacing the air filter
and the entire air path to the engine. The aerodynamically engineered
tube drives a massive amount of air into an engine, which translates
into POWER. 63 Series intake kits are not legal for street use in
some U.S. states.
