Used these guys before. Recently had a problem with a fiesta diesel rough running and one injector went down. Had the injectors removed and took all 4 to these guys. They tested and supplied me a second tested one and reconditioned the others. Turned around within 1 day excellent communication called and told me when they was ready. My mechanic refitted and the car is now running the best it ever has. Would recommend and will use again. Thank you
