Description
The STILLEN TruPower Cold Air Intake with Oiled Filter for the 2014–2021 Toyota Tundra 5.7L V8 is a true cold air intake system engineered to deliver maximum airflow, reduced intake air temperatures, and proven horsepower and torque gains. Developed over 18 months of testing and refinement, this system is designed for drivers who want performance gains without unnecessary complexity.
Unlike short-ram or under-hood intakes that pull in hot engine bay air, the TruPower system replaces the factory radiator shroud and intake ducting to route 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%.
During testing, the TruPower intake achieved ambient air temperatures up to 60 seconds faster than the factory intake and reached ambient conditions three times faster overall. Competing intake systems tested by STILLEN ran hotter than stock and failed to reach ambient temperatures entirely.
This configuration (TP403202) features a serviceable STILLEN oiled air filter paired with a direct-flow coupler, and does not include a block-off plate. It is intended for owners who want maximum airflow in normal driving conditions and do not require additional water-ingestion protection.
Vehicle Fitment
Fits the following vehicles:
- 2014-2021 Toyota Tundra
- 5.7L V8 engine only
Does NOT fit:
- 4.6L Tundra models
- Vehicles registered in California
Verify engine and emissions requirements before purchase.
Performance Gains
- Up to +20 horsepower*
- Up to +20 lb-ft of torque*
Horsepower gains may vary by vehicle. In addition to power improvements, the TruPower system significantly reduces intake air temperatures for more consistent performance.
Results may vary depending on vehicle condition, fuel quality, and environment.
