2022-Pres Toyota Tundra Intercooler Reservoir Relocation Kit Stillen

STILLEN Intercooler Reservoir Relocation Kit – 2022-Pres Toyota Tundra 3.4L Twin-Turbo V6

Optimize Cooling. Maximize Consistency. Drive with Confidence.

The STILLEN Intercooler Reservoir Relocation Kit is the solution the 2022-2025 Toyota Tundra twin-turbo V6 has been waiting for. During development of our TruPower by STILLEN Cold Air Intake and TruControl by STILLEN Tuning Module, we discovered a critical weakness in the factory intercooler setup: heat soak from the OEM cooling layout.

From the factory, the intercooler reservoir and radiator reservoir share a single combined wall-meaning the heat from your radiator system transfers directly into your intercooler system.

Whether you’re towing, cruising, or idling, that radiant heat preloads your intercooler fluid, hurting intake air temperatures and forcing the ECU to compensate with reduced timing and added fuel.

The STILLEN Intercooler Reservoir Relocation Kit separates the intercooler system from the radiator, giving it a dedicated path for thermal management. By divorcing the two systems and relocating the reservoir to a new position within the engine bay, this kit drastically improves cooling consistency and recovery time.

Proven Results. Real-World Testing.
Using an AEM AQ-1 Data Logger and additional sensors, we tested the OEM setup vs. our relocated intercooler system through real driving cycles-freeway pulls, idle time, and stop-and-go conditions.

Here’s what we found:

• Faster Cooldown: STILLEN system returned to operating temps in 2 minutes vs. OEM system never cooling down after 8+ minutes.
• Reduced Heat Soak: STILLEN setup reached lower peak temps and recovered over 4x faster than stock.
• More Stable IATs: Better thermal control means less timing pull and more consistent engine output.

This isn’t about chasing peak horsepower-it’s about maintaining consistent performance pull after pull, mile after mile.

Features:

• Eliminates OEM heat soak issue by relocating intercooler reservoir away from radiator system
• Improves cooling efficiency and consistency under load, during towing, and in high-temp conditions
• Quick installation – 30-60 minutes with basic tools
• Compatible with OEM and STILLEN intake systems
• Clean engine bay integration near the passenger side fender well
• OEM-style fit and finish
• Requires Toyota factory coolant for best performance and line integrity

Applications:

• 2022-Present Toyota Tundra with 3.4L Twin-Turbo V6
• Works with both OEM and aftermarket (TruPower by STILLEN) intake setups
• Unlock consistent performance and protect your twin-turbo Tundra from unnecessary heat soak.
• Upgrade to the STILLEN Intercooler Reservoir Relocation Kit today.
