Description
The STILLEN TruPower Cold Air Intake with Dry Filter for the 2014–2021 Toyota Tundra 5.7L V8 is a true cold air intake system engineered to deliver increased airflow, reduced intake air temperatures, and measurable horsepower and torque gains. Developed through 18 months of testing and refinement, this intake was designed to outperform short-ram and engine-bay intakes that suffer from heat soak.
The TruPower system replaces the factory radiator shroud and intake ducting to channel cold ambient air directly from the front of the vehicle, through the core support, and into a sealed airbox. This design utilizes the factory intake opening while increasing airflow capacity by nearly 50%, resulting in faster recovery to ambient air temperatures and improved performance consistency.
During testing, the TruPower intake reached ambient air temperatures up to 60 seconds faster than the factory intake and achieved ambient conditions three times faster overall. Competing intakes tested by STILLEN ran hotter than stock and failed to reach ambient temperatures.
This configuration (TP403203) features a washable, serviceable STILLEN dry air filter paired with a direct-flow (straight flow) coupler and does not include a block-off plate. It is ideal for drivers who want strong airflow performance with minimal maintenance and no oiling requirements.
