I've taken my car to 2 dealers and they were very cool with and didn't give me any problems with my mods. I actually called one before I went to see him and told him I had a CAI and a tune, And all he said was bring it in ( i brought it in to check out my clutch) and we will talk. Once I got there he looked at my car and said I see no problems ( meaning the CAI). He took the car on the road and on the lift and check out my clucth for me.

 

Tip your service advisor everytime you go in. no matter how small the job is. they'll remember you later.
