Bobbins were well packaged and looked good quality. I had a small slip with my 2005 5.4L F-150 when it was tilted slightly but hadn't coded yet. Replacing all the coils with this brand/product solved this problem and gave the motor back most of its original performance. Candles have changed to 130k but at 170k it's time for the coils. In my case, it's worth the time and money invested.
