The K&N performance airbox for BMW E90/91/93 335i N54 replaces the restrictive factory filter and housing to reduce airflow restriction and straighten intake flow. The enclosed injection-molded box and removable lid make filter access easy, supporting measurable power gains and easier maintenance. Backed by K&N's No-Hassle Lifetime Limited Warranty, this relatively easy-to-install intake fits the vehicle's original airbox space.
