DeutschTuning proudly offers Dinan Carbon Fiber Intake BMW 335i E90 07-10. 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 RPM's 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. Horsepower is increased by +14 Hp @ 6000 rpm and Torque is increased by +16ft-lbs @ 3400 rpm with Dinan Stage 3 Software, DINAN Intercooler and Free Flow Exhaust. Stage 2 software, Free Flow Exhaust produces 12 Hp and 13 ft-lb torque Stage 1 software, Free Flow Exhaust produces 9 Hp and 10 ft-lb torque Completely Stock car produces 5 Hp and 6 ft-lb torque Dinan Performance Software is highly recommended. Up to +14 HP & +16 lb/ft of TQ (with associated software and hardware upgrades upgrade), +5 HP & +6 lbs/ft TQ on a completely stock car. Replaces plastic airbox lid with a carbon fiber lid that adds a second air intake. Panel air filter for airbox as well as a conical air filter for the secondary intake are included. Includes shielding for the conical filter to protect it from hot engine compartment air. Air entering thru the Dinan intake is 40 degrees cooler than air comng in thru the stock intake. Stock intake tract stays completely functional. Mounting brackets and hardware included as well as hoses and hardware to delete the factory auxiliary radiator.
