We have a 2014 Taurus SHO. That had a Roush CAI. No tune, just the intake.
Car started developing issues with one of the turbo chargers. First thing replaced was the waste gate solenoid, but the issue resurfaced again. Dealer tech came up with some ridiculous comment that he has come to know that "these types of CAI are known to let dirt flow through and wear down the turbo impellers". Now keep in mind that the car only had 24K miles on it, and it's not like we drive the thing on dirt roads.
In the end the dealer replaced one of the turbos, but he insisted that the OEM intake be reinstalled in order to avoid future issues. They even offered to do the reinstall the intake without charging me.
Given that the repair order to replace the turbo was over $1,400, I had them do it.
I just didn't want to risk it in the event the other one went out, even though I think the claim that the filter is the cause of the turbo failure is ridiculous.
