I have a quick question. My car is in for B1 service. I removed my tune but kept the high flow K&N filters in (will be replaced with open cone soon). The technician pointed out that they have seen issues in the past with customers using these high flow filters but no tune that it has caused melted pistons .. but then said if car is tuned it should be fine. I asked to explain some more how some more air can damage a none tuned car...but wonder if anybody has every heard such a thing. Seems BS to me...

Drop-in filters with the OEM box? Yea no, that’s not gonna do a thing. When I had my large B service done, they removed my BMC drop-ins and replaced with new OEM paper filters - they put the BMC’s in a box in the trunk (they know they‘re valuable and reusable). No questions asked, they just did everything they needed for service (oil change, trans flush, etc.).
Sounds like he was trying to get you to admit to a tune in order to flag your car and void the warranty.
Yeah, came to my mind too. But did not fall for that trick if that what it was. I countered with .."oh, how many tuned once have you seen?" ...so far crickets.
It always amazes me how master technicians who are ASE certified and can tell you about how any oem mechanical system works on the car, can be so clueless when it comes to after market and performance aspects. Just because they know the car/engine does not mean they have a clue when talking about tunes, filters in this case, etc.
Most technicians nowadays do not have to be good at analysis, they just run scans and do what the machine and computer tells them.
You should be 100% fine running filters on a factory tune.
Anyone know if it would be fine to leave the ZAC intakes in during service?
It might be fine, but you will probably get a note made in the Tech department about your car or on the service record for any dealer to see. No good could come from it. Considering how easy the intakes are to put on, I would spend the 10 minutes and re install the factory and takes just to be safe.
