Trupower Cold Air Intake

The Stillen Trupower by STILLEN Cold Air Intake is engineered as the only true cold air intake for the 2014+ Toyota Tundra 5.7 liter. Developed over 18 months, this system significantly increases airflow while dramatically reducing intake air temperatures. It utilizes a replacement radiator shroud and intake duct to draw cold air from the front of the vehicle, channeling it through the truck's core support into a large airbox. This design leverages the factory air intake opening while adding nearly 50% more airflow. Testing by the STILLEN product development team showed intake air temperatures dropping three times faster than the factory air intake, outperforming competitor intakes that ran hotter than stock. The system is also noted for achieving ambient air temperatures 60 seconds faster than the factory setup. This specific configuration, TP403201, includes a removable block-off plate and free-flow tube, recommended for customers who deal with extreme conditions. The block-off plate can be installed in under five minutes. A serviceable STILLEN dry filter with a limited lifetime warranty is included, and the intake is made in the USA with easy installation requiring no cutting or modifications. Note that this product is not for sale in California.
