I put an aftermarket cold air intake system from another shop. I brought my car in to Andy and Ron to look at what i did. They said Iam doing more damage than good and suggested i install the Dinan Cold Air Intake and Chip. My BMW has 67,000 miles on it and it has never run this good. The guys at Performing Imports could be the most knowledge of anyone i have ever met on what is best for my BMW. I will bring all my service business to these guys. Plus, they are nice guys Don't you just love car guys
