# Introducing the STILLEN Intercooler Reservoir Kit for the 2024+ Toyota Tundra

### **The Weak Link in the Tundra's Twin-Turbo Setup**

The 2022-2025 Toyota Tundra 3.4L twin-turbo V6 is a powerhouse — but like every great platform, it has a weak spot. During development of [TruPower by STILLEN Cold Air Intake](https://stillen.com/collections/intake/Toyota-Tundra-2022) and the [TruControl by STILLEN Tuning Module](https://stillen.com/collections/electronics/Toyota-Tundra-2022), STILLEN's engineers uncovered a critical issue in the factory intercooler system: heat soak caused by the OEM cooling layout.

From the factory, Toyota designed the radiator reservoir and the intercooler reservoir to share a single wall. That means radiant heat from the radiator preloads the intercooler fluid before you even hit the throttle. The result is hotter intake air temperatures, ignition timing pulled by the ECU, and less consistent performance — whether you're towing, cruising, or sitting in traffic.

### **The STILLEN Solution**

The [STILLEN Intercooler Reservoir Relocation Kit](https://stillen.com/collections/coolers/products/2022-2025-toyota-tundra-intercooler-reservoir-relocation-kit-401200) fixes this issue by separating the radiator and intercooler systems. Instead of sharing heat, your intercooler fluid now has its own dedicated thermal path. By relocating the reservoir to a new position in the engine bay, STILLEN keeps temps stable and improves recovery time after heat soak.

The result is simple: more consistent intake air temperature and performance, mile after mile.

### **Real-World Tested, Proven Results**

STILLEN doesn't just make parts — the team tests them. Using an AEM AQ-1 data logger with additional sensors, engineers compared the OEM setup to the STILLEN Intercooler Reservoir in real driving conditions: freeway pulls, idle time, and stop-and-go traffic.

Here's what they found:

-   **Faster cooldown:** The STILLEN system returned to safe temps in just 2 minutes. The OEM system was still heat-soaked after 8+ minutes.
-   **Reduced heat soak:** The STILLEN system hit lower peak temps and recovered 4x faster than stock.
-   **Stable intake air temperatures:** Better cooling means less timing pulled and more reliable engine output.

This upgrade isn't about chasing peak horsepower — it's about keeping your Tundra consistent, especially under heavy load or high-temperature conditions.
