About this part

Product Details

If you're looking to get more airflow into your BMW Z3 2.0 24V 6CYL DOHC from 1999-2000, this K&N 57i Performance Intake Kit is a solid option. It's designed to replace your restrictive factory air box, allowing your engine to breathe more freely. This can lead to improved performance across the entire RPM range, giving you a more responsive feel when you press the accelerator.

This kit includes a large, washable K&N air filter that connects directly or indirectly to your engine's throttle body via a sturdy adapter tube. The extra surface area of the K&N filter means it can hold more dirt than a standard replacement filter, extending the time between cleanings – often up to 100,000 miles. The adapters are made from durable materials like steel or aluminum to ensure they hold up under the hood. This intake system is designed to fit a range of BMW models, including the 323i, 325Ci, and 328i, among others.

Keep in mind that this intake system is not legal for sale or use in California and other states that have adopted California's emissions standards. It comes with K&N's No-Hassle Lifetime Limited Warranty and Million Mile Limited Warranty for peace of mind.
