air intake stack for BMW E46 320 323 325 328


Performance Air intake kit for BMW E46 320 323 325 328 – all models



This air intake kit specifically designed for the BMW E46 dramatically improves air flow by up-to 12%, compared to the restrictive OEM air box/filter and factory air inlet duct.

Your engine effectively functions as a giant air compressor. Feeding more air to your engine is a great way to improve power, especially if it’s cooler, denser air.

Easy to install kit includes a washable, reusable air filter element and low restriction duct.
