Description
Factory air filters restrict airflow to protect your engine from debris, but they also cost you horsepower and throttle response. The K&N BM-1324 replaces this compromise with a high-flow cotton media design that delivers measurable power gains while maintaining OEM-level filtration and durability. Since it’s washable and reusable, you’ll recoup the investment within a few service cycles while enjoying crisp acceleration every time you drive.
