KY Smog & Test Only (加恩汽車排煙檢測中心) is a STAR Certified Smog Inspection Station that serves the cities of Monterey Park and its neighboring cities Alhambra, East Los Angeles, Montebello, Rosemead, South Pasadena and the greater Los Angeles area.

Dennis "Kai Yee" Hui, a long-time Monterey Park resident started KY Smog & Test Only in May 2010 after diligently working for other automotive employers for 23 years. In 2017, his son Matthew assumed the responsibilities of manager and technician of KY Smog & Test Only continuing on in the legacy that his father Dennis left behind in treating all customers with prompt and courteous service.  

Why are we the best Smog Check station in Monterey Park, Alhambra, Montebello, South Pasadena, East Los Angeles, Rosemead, and the surrounding San Gabriel Valley? With over 25 years of experience, we have seen cars from all makes and models and are more than happy to help you navigate through the muddy (and sometimes unclear) process of vehicle registration and change of ownership. 

Our business is dedicated to making the process of getting your car smog certified for auto registration renewal and change of ownership transfers straightforward and seamless. We also are able to provide smog test certification for out of state vehicles looking to register in California, Diesel and hybrid vehicles.
