Description
The STILLEN TruPower Cold Air Intake with Oiled Filter for the 2022–2025 Toyota Tundra and 2023–2025 Toyota Sequoia 3.4L Twin-Turbo V6 is the only true cold air intake system engineered specifically for Toyota’s latest turbocharged truck and SUV platforms.
After nearly two years of development and real-world testing, STILLEN designed an intake that does what most aftermarket systems fail to do—deliver consistent ambient air temperatures while increasing airflow and power. Unlike short-ram or under-hood intakes that suffer from heat soak, the TruPower system pulls genuine cold air directly from the front of the vehicle, not the engine bay.
The TruPower intake replaces the factory intake scoops and ducting with dual fresh-air channels, routing cold ambient air through the core support into a larger, sealed airbox. This design utilizes both the factory intake opening and a secondary fresh air source, resulting in nearly 50% increased airflow capacity over the OEM system.
Vehicle Fitment
Fits the following vehicles:
- 2022-2025 Toyota Tundra
- 2023-2025 Toyota Sequoia
- 3.4L Twin-Turbo V6 engines only
Does NOT fit:
- Vehicles registered in California
- Non-3.4L engine configurations
Always verify engine configuration and emissions compliance before purchase.
Performance Gains
- Up to +11 horsepower*
- Up to +22 lb-ft of torque*
These gains are achieved through increased airflow and dramatically faster recovery to ambient intake air temperatures across real-world driving conditions.
Results may vary.
Intake Air Temperature Testing
During extensive highway testing (65–70 mph), the TruPower intake consistently outperformed the factory system:
- TruPower reached ambient air temperature within ¼ mile (~20 seconds)
- Factory intake required over 3 miles and nearly 3 minutes and still remained 3–5°F above ambient
- Even after 10 minutes of steady cruising, the OEM intake never fully achieved ambient temperature
- Factory intake only reached ambient during hard acceleration—and immediately heat-soaked once throttle was reduced
This testing confirms that the TruPower system lowers intake air temperatures up to 12 times faster than OEM, delivering cooler, denser air under real driving conditions—not just on a dyno.

Why Choose STILLEN TruPower?
Many intakes increase noise but fail to deliver cooler air where it matters. The TruPower system was engineered from the ground up to provide real intake temperature reduction, consistent airflow, and proven power gains—all while maintaining factory-level fitment and reliability.
For the 3.4L twin-turbo Tundra and Sequoia, this intake should be considered one of the first performance upgrades.
