I had been looking for quite some time for a tuning shop to install japanese domestic market (aftermarket) parts on my MX-5 ND Club model in Orange County. I was driving to LA near the airport as recommended by several sources before I found Yoshi. I have now utilized Yoshi (owner, service provider) twice for parts that were obviously tedious and difficult to install. Yoshi demonstrates an amazing amount of persistence and pride in his service skills. I have nothing but respect for Yoshi and his tuning shop in Huntington Beach. I bring my car to him from Dana Point. A relatively short drive with use of the toll road. My recommendation provided without reservation

If you have anything rotary, look no further than this shop. Yoshi is a master of his craft, and has the attention to detail you need when dealing with our finicky motors. He got my RX-8 back up and running, and advised me on care & maintenance procedures that I otherwise would not have known. I will not be taking my RX-8 anywhere else. Thanks Yoshi!

I come here for all my rx8 needs and everytime he does amazing work. I've done my clutch, brakes, oil and coolant changes all here. I would recommend if you have a rotary as well.
