PLM Power Driven Audi Reservoir Kit – Audi S4 / Audi S4 / Audi A4 / Audi A4

SKU: PLM-AUDI-B8-RESERVOIR

Heat is the enemy of performance, especially on supercharged Audi platforms. As boost pressure and power levels increase, intake air temperatures rise rapidly, leading to heat soak and reduced output. The PLM Power Driven Reservoir Kit is designed to expand your cooling system capacity, stabilize temperatures, and keep your vehicle performing consistently under demanding conditions.

Unlike bulky, under-hood add-ons that clutter the engine bay, this reservoir is cleverly engineered to mount behind the factory bumper, remaining completely hidden once installed while delivering a serious functional upgrade.

By adding approximately 4 liters of additional coolant capacity, the system allows for greater thermal stability, slower temperature rise, and faster recovery between pulls. The result is more reliable power delivery whether you are daily driving, road racing, or making repeated wide-open throttle runs.

Constructed from full aluminum for strength, durability, and optimal heat management, this kit integrates cleanly with your factory cooling system and can be installed with standard hand tools.

Why Upgrade the Reservoir?

More coolant volume means:

• Better resistance to heat soak

• Lower and more stable intake air temperatures

• Improved consistency during aggressive driving

• Added protection for tuned or higher-boost vehicles
