Product Information
All Direnza Cold Air Induction Systems are supplied with a high quality, cone style air filter; designed to replace the OEM BMW airbox, offering more surface area compared to the standard filter. Direnza air filters are manufactured from premium grade, washable cotton, ensuring long-lasting performance enhancements.
Direnza Cold Air Induction Kits include lightweight alloy pipework mandrel-bent for accurate placement on your E85 Z4, and coated with a premium grade, black textured finish for a sleek appearance.
Designed in-house by Direnza engineers, our Cold Air Induction Kits reduce blockages and significantly enhance air flow into the 2.0L engine compared with stock induction arrangements, boosting your Z4’s soundtrack and performance.
Heat-resistant silicone hoses are supplied with every Direnza Cold Air Induction Kit. An often-overlooked item, our easy-fit silicones are layered for extra durability, their 5mm wall consisting of four polyester layers finished with jet black pigment.
