K&N Intake System (Cold Air / Performance Intake): replaces the restrictive factory assembly to improve airflow to the engine through an optimized duct and a high-performance filter.
Less restriction: the design smooths and straightens the airflow so the engine can inhale more useful air.
Performance: in many vehicles, it is aimed at providing a gain in power and response (depending on application).
K&N Filtration: depending on the kit, it can come with a DRYFLOW synthetic filter without oil or oiled cotton, both designed for high flow.
Guided installation: kits come with step-by-step instructions; installation is usually done with basic tools.
Note: check applicable regulations/homologation for public road use and filter maintenance according to the included type.
