This IS THE PLACE to have your injectors cleaned. I was impressed with the shop cleanliness and top quality equipment, also the owner is a life long mechanic who is very friendly and freely volunteered advice. My BMW now has smooth & strong power, NO rough engine, NO misfire codes. Cleaning all 6 injectors cost much less than purchasing a single injector, all new O-rings were included, turn around time was a couple hours. Very professional expedience, highly recommended.
