Beat the heat and boost your vehicle's performance with our purpose-built trunk water/ice tank system designed exclusively for your 2009 - 2014 Cadillac CTS-V. When stock cooling systems falter under the stress of high boost and rising air temperatures, our system stands strong, ensuring your engine doesn't lose power due to overreaching intake air temperatures (IAT).

Crafted with a unique sump setup, this tank system outperforms traditional flat tank designs by ensuring superior water scavenging. It perfectly fits in your CTS-V's trunk tire well, melding into your car's architecture like it was always meant to be there.

Hold a whopping 7.5 gallons of cooling fluid in this behemoth of a tank, equivalent to a kiddie pool! Plus, the tank includes a -10AN drain port, with the drain kit sold separately.
