I installed this Quantum Pro cooler in a customer's 997 at the end of 2023, he used the car once with the system and decided to go a different route (icebox). These systems are great and effective and less hassle than the aforementioned icebox. I've run one for 24 hours at VIR in August with no issues (not this unit!). New price for this system is $3999 plus accessories- in this case around $4400 with the carbon plenum and 6ft hose. Don't miss out.
