Does the 2015 have the same potential for early heater core plugging the 2012's did? Mine has 60k and I wanted to address this and any other potential issues. The Malone stage 2 is incredible especially with the 6mt.

It’s the same heater core. They claim they’ve upgraded it and are using different flux now, but the problem still occurs. Make sure you flush the system well when you do this or it could clog again in as little as 3 weeks

Good luck

Just my uneducated guess. Malone won't help the heater core as it harsher on EGTs thus harsher on coolant especially for the W2A IC.

I'll be planning a fluid flush at 60K.
