Description
The STILLEN TruPower Cold Air Intake with Dry Filter is the only true cold air intake system designed for the 2022–2025 Toyota Tundra and 2023–2025 Toyota Sequoia 3.4L Twin-Turbo V6. After nearly two years of development and rigorous testing, STILLEN engineered an intake that delivers faster ambient air recovery, cooler intake temperatures, and improved engine airflow—all while remaining completely bolt-on and serviceable.
Unlike conventional aftermarket intakes, the TruPower system pulls genuine cold air from outside the engine bay, using dual scoops and ducts to channel air from the front of the vehicle into a larger, sealed airbox. With a secondary fresh-air source, the TruPower intake provides nearly 50% more airflow over the OEM system, resulting in noticeable power and torque gains.
Vehicle Fitment
Fits the following vehicles:
- 2022-2025 Toyota Tundra
- 2023-2025 Toyota Sequoia
Engine Compatibility: 3.4L Twin-Turbo V6 only
Exclusions: Not for sale in California
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 by delivering cooler, denser air to the engine while maintaining high airflow efficiency throughout the rev range.
Results may vary.
Intake Air Temperature Performance
In real-world testing at highway speeds (65–70 mph):
- The TruPower intake achieved ambient air temperature in just ¼ mile (~20 seconds)
- OEM intake took over 3 miles (~3 minutes) and remained 3–5°F above ambient
- Even after 10 minutes of steady cruising, OEM intake never fully reached ambient
- OEM intake only reached ambient under wide-open throttle and heat-soaked immediately upon easing off
The TruPower system’s dry filter configuration ensures consistent cool air delivery in extreme dust or off-road conditions, where oiled filters may collect contaminants more quickly.

Why Choose STILLEN TruPower?
Many aftermarket intakes increase noise but fail to deliver true cold air to the engine. The TruPower system lowers intake air temperatures, maximizes airflow, and provides measurable power gains, all while maintaining OEM-quality fit and reliability. For 3.4L twin-turbo Tundra and Sequoia owners, the TruPower intake should be one of the first performance upgrades.
