Carbon Fiber Cold Air Intake

The Dinan Carbon Fiber Cold Air Intake is meticulously engineered to enhance airflow and boost performance for the E38 BMW 740i. This aggressive system replaces the stock air box with a high-flow, cylindrical performance filter and a precisely optimized 4-inch diameter carbon fiber intake tube, designed to minimize turbulence and maximize airflow efficiency. The filter's strategic relocation to a compartment behind the front bumper and below the headlights is key to its performance. This placement insulates it from engine compartment heat, ensuring it draws in the coolest, densest, and most oxygen-rich air possible, leading to improved engine efficiency and lower intake air temperatures. The updated design features a more durable, embossed Dinan logo, a significant aesthetic improvement over older Mylar decals. Coupled with engine software, it can achieve maximum power increases of up to +21 HP and +20 LB-FT, along with improved throttle response. The use of a larger cylindrical filter further enhances flow capabilities, while the carbon fiber construction provides a premium, showroom-ready appearance. This intake is also 50-State Emissions Legal, bearing CARB EO D-176-27.
