Kohlefaser Luft-Technik Open-To-Enclosed Upgrade Kit
If you already have the ECS open cone filter for you N54 car then this is the perfect add-on upgrade for your system to really clean up the engine bay and keep your cone filters much cleaner. When you upgrade to the enlcosed filter kit your filters will be surrounded more more consistent cold air and by protecting the filter from engine bay dirt you are reducing the risk of air flow problems from build up.
The ECS Kohlefaser Luft-Technik (Carbon Fiber Air Technology) intake for the 135/335/535 is a beautifully crafted dual-cone intake with a glossy carbon fiber enclosure. Developed in-house using ECS's chassis dyno and state of the art laser scanning and 3D CAD technology, the N54 carbon airbox is a direct replacement for the stock system. Laser scanning allows ECS to produce a finished product that is a perfect fit to the engine bay. All tubing is also made from carbon fiber with each piece designed for optimal flow. The carbon fiber sandwiches a special heat-blocking fiberglass core, insulating the air box from engine bay heat. All of this combines to produce more power and torque over a wider RPM range - up to 13ft-lbs and 18hp when combined with a Cobb software tune, FMIC, and exhaust. And it looks amazing every time you open the hood.
Features:
- Designed and engineered using CAD technology for optimal flow and fitment
- Stainless steel hardware
- Direct replacement for stock air box; integrates seamlessly with stock intake piping
- Beautiful and functional carbon fiber/e-fiberglass construction
