aFe 20-21 BMW Z4 M40i (G29) L6-3.0L (t) B58 Track Series Intake System w/ Pro 5R Filter - 57-10017R

This 7” tall 360-degree radial flow air filter features a 4” oval flange and our oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum airflow and performance. This media is best suited for street and track use. The included massive air filter is surrounded by an open-element XLPE (cross-linked polyethylene) polymer housing that minimizes warm engine air for maximum performance. Its open design allows for easy viewing of the air filter and delivers an aggressive air intake sound. The lightweight tube is computer-designed to achieve maximum power gains while maintaining a perfect fit. Manufactured from 100% twill weave carbon fiber, it features zero fiberglass and is clear-coated for the highest quality construction. This intake is designed to use factory mounting locations, minimizing the use of unnecessary hardware, ensuring a perfect fit every time. Its revolutionary design, featuring our patent pending filter-to-housing interface uses half the number of parts of a traditional cold air intake system. Stainless-steel clamps are included for strength, and a premium bellows coupling allows for ample flexibility. This intake is designed to fit models equipped with the factory strut brace, with no modification required.
