2016 Mazda cold air intake problems
Buying a used 2016 mazda 6 from a dealership. The previous owner installed
an injen cold air intake. During the test drive I didn't noticed any idling
problems and it handled well. I'm worried he installed something else
internally that could take affect after the purchase. Also the brake fluid was
low so I have reason to suspect a leak or something. I don't know cars very
well and any suggestions and advice would be greatly appreciated!
