Brought my 2013 X5 50i M sport to Foreign Tech to get some motor work done. BMW dealerships wanted me to put in a new motor out of pocket for the troublesome N63 motor. Said that it couldn’t be done. I left it with The guys at Foreign tech and they fixed it without a problem, they are even approved by my third party warranty for all the work. They were able to go back and forth working with the warranty company to get approval on my claim. I had to do nothing for it! They did it all for me. After they completed the motor work that BMW said they couldn’t, I had them build custom straight pipes and let me tell you, it sounds amazing. There are very few performance upgrades for this truck. I was so happy with the quality of their work I have since brought them my e36 M3 coupe to work on. New or old I would trust them with my vehicles.
