Dinan Cold Air Intake - 2007-2010 BMW 135i/335i D760-0031

As boost is increased through the use of performance software, the single factory intake becomes restrictive and the engine is lacking the air it needs to make maximum power. Our cold air intake force feeds the 3-liter turbocharged inline 6 with greater volumes of cool oxygen-rich air for substantial power gains by utilizing our secondary carbon fiber intake. The system is so effective that the carbon fiber inlet air temperature is a full 40 degrees Fahrenheit cooler than the incoming air from the stock inlet. Due to the increased airflow from our intake, the power-curve is extended into the higher RPMs for a noticeable change. The system is a direct replacement for the factory air box lid, employing a hand-crafted carbon fiber unit that also includes a secondary carbon fiber intake tube that captures cool air from the lower grill and includes the shielding for the conical filter to insulate it from power-robbing engine compartment heat.
