Description
The STILLEN Intercooler Reservoir Relocation Kit for the 2022–2025 Toyota Tundra and 2023–2025 Toyota Sequoia 3.4L Twin-Turbo V6 is a precision-engineered solution designed to eliminate heat soak issues from the factory intercooler setup. By relocating the intercooler reservoir away from the radiator system, this kit significantly improves cooling efficiency, reduces intake air temperatures, and ensures consistent engine performance under heavy loads, towing, or high ambient temperatures.
This kit installs directly into the engine bay with basic hand tools and no cutting or modifications required, typically taking 30–60 minutes. Once installed, drivers benefit from faster thermal recovery, reduced heat soak, and more stable engine output, allowing the twin-turbo system to perform consistently during repeated hard pulls or long drives.
Real-world testing shows the STILLEN system cools in approximately 2 minutes, compared to over 8 minutes for the OEM setup. Heat soak is reduced, and intake air temperatures recover over four times faster than stock, keeping engine timing and performance consistent even under extreme conditions. The kit integrates cleanly near the passenger-side fender well for an OEM-style appearance and is fully compatible with Toyota factory coolant and both OEM and STILLEN intake systems.
