Last time I went to a dealer the kid they had working on my car went into my glove compartment grabbed a tazer I had in there and “accidentally“ shot it off. Luckily it didn’t hit anyone. Never again.
Ordered 2 of them from Amazon, they work pretty well so far. It attaches to the ac vent with a clamp & the hose can stretch about 10 feet. They stay locked on to the vents with minimal cool air leakage which is nice.

Question for the OP. When you take the vehicle to the dealer for service, I assume you will flash back to stock, in which case the DIY is more convenient because you don’t have to make an appointment/meet up with your tuner guy to go back to stock (then again to re-flash), is this correct?
